About this + document... + + Previous Page Up one Level Next Page GNU Mailman - Installation Manual + __________________________________________________________________ + +GNU Mailman - Installation Manual + + Barry Warsaw + + barry (at) list dot org + + Release 2.1 + December 5, 2007 + + Front Matter + + Abstract: + + This document describes how to install GNU Mailman on a POSIX-based + system such as Unix, MacOSX, or GNU/Linux. It will cover basic + installation instructions, as well as guidelines for integrating + Mailman with your web and mail servers. + + The GNU Mailman website is at http://www.list.org + + 1 Installation Requirements + + Please note that the information on this page may be out of date. Check + for the latest installation information on the Mailman wiki. + + GNU Mailman works on most POSIX-based systems such as Unix, MacOSX, or + GNU/Linux. It does not currently work on Windows. You must have a mail + server that you can send messages to, and a web server that supports + the CGI/1.1 API. Apache makes a fine choice for web server, and mail + servers such as Postfix, Exim, Sendmail, and qmail should work just + fine. + + To install Mailman from source, you will need an ANSI C compiler to + build Mailman's security wrappers. The GNU C compiler gcc works well. + + You must have the Python interpreter installed somewhere on your + system. As of this writing, Python 2.4.4 is recommended, but see the + wiki page above for the latest information. + + 2 Set up your system + + Before installing Mailman, you need to prepare your system by adding + certain users and groups. You will need to have root privileges to + perform the steps in this section. + +2.1 Add the group and user + + Mailman requires a unique user and group name which will own its files, + and under which its processes will run. Mailman's basic security is + based on group ownership permissions, so it's important to get this + step right^1. Typically, you will add a new user and a new group, both + called mailman. The mailman user must be a member of the mailman group. + Mailman will be installed under the mailman user and group, with the + set-group-id (setgid) bit enabled. + + If these names are already in use, you can choose different user and + group names, as long as you remember these when you run configure. If + you choose a different unique user name, you will have to specify this + with configure's --with-username option, and if you choose a different + group name, you will have to specify this with configure's + --with-groupname option. + + On Linux systems, you can use the following commands to create these + accounts. Check your system's manual pages for details: + + % groupadd mailman + % useradd -c''GNU Mailman'' -s /no/shell -d /no/home -g mailman mailman + +2.2 Create the installation directory + + Typically, Mailman is installed into a single directory, which includes + both the Mailman source code and the run-time list and archive data. It + is possible to split the static program files from the variable data + files and install them in separate directories. This section will + describe the available options. + + The default is to install all of Mailman to /usr/local/mailman^2. You + can change this base installation directory (referred to here as + $prefix) by specifying the directory with the --prefix configure + option. If you're upgrading from a previous version of Mailman, you may + want to use the --prefix option unless you move your mailing lists. + + Warning: You cannot install Mailman on a filesystem that is mounted + with the nosuid option. This will break Mailman, which relies on setgid + programs for its security. If this describes your environment, simply + install Mailman in a location that allows setgid programs. + + Make sure the installation directory is set to group mailman (or + whatever you're going to specify with --with-groupname) and has the + setgid bit set^3. You probably also want to guarantee that this + directory is readable and executable by everyone. For example, these + shell commands will accomplish this: + + % cd $prefix + % chgrp mailman . + % chmod a+rx,g+ws . + + You are now ready to configure and install the Mailman software. + + 3 Build and install Mailman + +3.1 Run configure + + Before you can install Mailman, you must run configure to set various + installation options your system might need. + + Note: Take special note of the --with-mail-gid and --with-cgi-gid + options below. You will probably need to use these. + + You should not be root while performing the steps in this section. Do + them under your own login, or whatever account you typically use to + install software. You do not need to do these steps as user mailman, + but you could. However, make sure that the login used is a member of + the mailman group as that that group has write permissions to the + $prefix directory made in the previous step. You must also have + permission to create a setgid file in the file system where it resides + (NFS and other mounts can be configured to inhibit setgid settings). + + If you've installed other GNU software, you should be familiar with the + configure script. Usually you can just cd to the directory you unpacked + the Mailman source tarball into, and run configure with no arguments: + + % cd mailman-<version> + % ./configure + % make install + + The following options allow you to customize your Mailman installation. + + --prefix=dir + Standard GNU configure option which changes the base directory + that Mailman is installed into. By default $prefix is + /usr/local/mailman. This directory must already exist, and be + set up as described in 2.2. + + --exec-prefix=dir + Standard GNU configure option which lets you specify a different + installation directory for architecture dependent binaries. + + --with-var-prefix=dir + Store mutable data under dir instead of under the $prefix or + $exec_prefix. Examples of such data include the list archives + and list settings database. + + --with-python=/path/to/python + Specify an alternative Python interpreter to use for the wrapper + programs. The default is to use the interpreter found first on + your shell's $PATH. + + --with-username=username-or-uid + Specify a different username than mailman. The value of this + option can be an integer user id or a user name. Be sure your + $prefix directory is owned by this user. + + --with-groupname=groupname-or-gid + Specify a different groupname than mailman. The value of this + option can be an integer group id or a group name. Be sure your + $prefix directory is group-owned by this group. + + --with-mail-gid=group-or-groups + Specify an alternative group for running scripts via the mail + wrapper. group-or-groups can be a list of one or more integer + group ids or symbolic group names. The first value in the list + that resolves to an existing group is used. By default, the + value is the list mailman, other, mail, and daemon. + + Note: This is highly system dependent and you must get this + right, because the group id is compiled into the mail wrapper + program for added security. On systems using sendmail, the + sendmail.cf configuration file designates the group id of + sendmail processes using the DefaultUser option. (If commented + out, it still may be indicating the default...) + + Check your mail server's documentation and configuration files + to find the right value for this switch. + + --with-cgi-gid=group-or-groups + Specify an alternative group for running scripts via the CGI + wrapper. group-or-groups can be a list of one or more integer + group ids or symbolic group names. The first value in the list + that resolves to an existing group is used. By default, the + value is the the list www, www-data, and nobody. + + Note: The proper value for this is dependent on your web server + configuration. You must get this right, because the group id is + compiled into the CGI wrapper program for added security, and no + Mailman CGI scripts will run if this is incorrect. + + If you're using Apache, check the values for the Group option in + your httpd.conf file. + + --with-cgi-ext=extension + Specify an extension for cgi-bin programs. The CGI wrappers + placed in $prefix/cgi-bin will have this extension (some web + servers require an extension). extension must include the + leading dot. + + --with-mailhost=hostname + Specify the fully qualified host name part for outgoing email. + After the installation is complete, this value can be overriden + in $prefix/Mailman/mm_cfg.py. + + --with-urlhost=hostname + Specify the fully qualified host name part of urls. After the + installation is complete, this value can be overriden in + $prefix/Mailman/mm_cfg.py. + + --with-gcc=no + Don't use gcc, even if it is found. In this case, cc must be + found on your $PATH. + +3.2 Make and install + + Once you've run configure, you can simply run make, then make install + to build and install Mailman. + + 4 Check your installation + + After you've run make install, you should check that your installation + has all the correct permissions and group ownerships by running the + check_perms script. First change to the installation (i.e. $prefix) + directory, then run the bin/check_perms program. Don't try to run + bin/check_perms from the source directory; it will only run from the + installation directory. + + If this reports no problems, then it's very likely <wink> that your + installation is set up correctly. If it reports problems, then you can + either fix them manually, re-run the installation, or use + bin/check_perms to fix the problems (probably the easiest solution): + + * You need to become the user that did the installation, and that + owns all the files in $prefix, or root. + * Run bin/check_perms -f + * Repeat previous step until no more errors are reported! + + Warning: If you're running Mailman on a shared multiuser system, and + you have mailing lists with private archives, you may want to hide the + private archive directory from other users on your system. In that + case, you should drop the other execute permission (o-x) from the + archives/private directory. However, the web server process must be + able to follow the symbolic link in public directory, otherwise your + public Pipermail archives will not work. To set this up, become root + and run the following commands: + +# cd <prefix>/archives +# chown <web-server-user> private +# chmod o-x private + + You need to know what user your web server runs as. It may be www, + apache, httpd or nobody, depending on your server's configuration. + + 5 Set up your web server + + Congratulations! You've installed the Mailman software. To get + everything running you need to hook Mailman up to both your web server + and your mail system. + + If you plan on running your mail and web servers on different machines, + sharing Mailman installations via NFS, be sure that the clocks on those + two machines are synchronized closely. You might take a look at the + file Mailman/LockFile.py; the constant CLOCK_SLOP helps the locking + mechanism compensate for clock skew in this type of environment. + + This section describes some of the things you need to do to connect + Mailman's web interface to your web server. The instructions here are + somewhat geared toward the Apache web server, so you should consult + your web server documentation for details. + + You must configure your web server to enable CGI script permission in + the $prefix/cgi-bin to run CGI scripts. The line you should add might + look something like the following, with the real absolute directory + substituted for $prefix, of course: + + Exec /mailman/* $prefix/cgi-bin/* + + or: + + ScriptAlias /mailman/ $prefix/cgi-bin/ + + Warning: You want to be very sure that the user id under which your CGI + scripts run is not in the mailman group you created above, otherwise + private archives will be accessible to anyone. + + Copy the Mailman, Python, and GNU logos to a location accessible to + your web server. E.g. with Apache, you've usually got an icons + directory that you can drop the images into. For example: + + % cp $prefix/icons/*.{jpg,png} /path/to/apache/icons + + You then want to add a line to your $prefix/Mailman/mm_cfg.py file + which sets the base URL for the logos. For example: + + IMAGE_LOGOS = '/images/' + + The default value for IMAGE_LOGOS is /icons/. Read the comment in + Defaults.py.in for details. + + Configure your web server to point to the Pipermail public mailing list + archives. For example, in Apache: + + Alias /pipermail/ $varprefix/archives/public/ + + where $varprefix is usually $prefix unless you've used the + --with-var-prefix option to configure. Also be sure to configure your + web server to follow symbolic links in this directory, otherwise public + Pipermail archives won't be accessible. For Apache users, consult the + FollowSymLinks option. + + If you're going to be supporting internationalized public archives, you + will probably want to turn off any default charset directive for the + Pipermail directory, otherwise your multilingual archive pages won't + show up correctly. Here's an example for Apache, based on the standard + installation directories: + + <Directory "/usr/local/mailman/archives/public/"> + AddDefaultCharset Off + </Directory> + + Now restart your web server. + + 6 Set up your mail server + + This section describes some of the things you need to do to connect + Mailman's email interface to your mail server. The instructions here + are different for each mail server; if your mail server is not + described in the following subsections, try to generalize from the + existing documentation, and consider contributing documentation updates + to the Mailman developers. + +6.1 Using the Postfix mail server + + Mailman should work pretty much out of the box with a standard Postfix + installation. It has been tested with various Postfix versions up to + and including Postfix 2.1.5. + + In order to support Mailman's optional VERP delivery, you will want to + disable luser_relay (the default) and you will want to set + recipient_delimiter for extended address semantics. You should comment + out any luser_relay value in your main.cf and just go with the + defaults. Also, add this to your main.cf file: + + recipient_delimiter = + + + Using "+" as the delimiter works well with the default values for + VERP_FORMAT and VERP_REGEXP in Defaults.py. + + When attempting to deliver a message to a non-existent local address, + Postfix may return a 450 error code. Since this is a transient error + code, Mailman will continue to attempt to deliver the message for + DELIVERY_RETRY_PERIOD - 5 days by default. You might want to set + Postfix up so that it returns permanent error codes for non-existent + local users by adding the following to your main.cf file: + + unknown_local_recipient_reject_code = 550 + + Finally, if you are using Postfix-style virtual domains, read the + section on virtual domain support below. + + 6.1.1 Integrating Postfix and Mailman + + You can integrate Postfix and Mailman such that when new lists are + created, or lists are removed, Postfix's alias database will be + automatically updated. The following are the steps you need to take to + make this work. + + In the description below, we assume that you've installed Mailman in + the default location, i.e. /usr/local/mailman. If that's not the case, + adjust the instructions according to your use of configure's --prefix + and --with-var-prefix options. + + Note: If you are using virtual domains and you want Mailman to honor + your virtual domains, read the 6.1 section below first! + + * Add this to the bottom of the $prefix/Mailman/mm_cfg.py file: + MTA = 'Postfix' + + The MTA variable names a module in the Mailman/MTA directory which + contains the mail server-specific functions to be executed when a + list is created or removed. + * Look at the Defaults.py file for the variables POSTFIX_ALIAS_CMD + and POSTFIX_MAP_CMD command. Make sure these point to your + postalias and postmap programs respectively. Remember that if you + need to make changes, do it in mm_cfg.py. + * Run the bin/genaliases script to initialize your aliases file. + % cd /usr/local/mailman + % bin/genaliases + + Make sure that the owner of the data/aliases and data/aliases.db + file is mailman, that the group owner for those files is mailman, + or whatever user and group you used in the configure command, and + that both files are group writable: + % su + % chown mailman:mailman data/aliases* + % chmod g+w data/aliases* + + * Hack your Postfix's main.cf file to include the following path in + your alias_maps variable: + /usr/local/mailman/data/aliases + + Note that there should be no trailing .db. Do not include this in + your alias_database variable. This is because you do not want + Postfix's newaliases command to modify Mailman's aliases.db file, + but you do want Postfix to consult aliases.db when looking for + local addresses. + You probably want to use a hash: style database for this entry. + Here's an example: + alias_maps = hash:/etc/postfix/aliases, + hash:/usr/local/mailman/data/aliases + + * When you configure Mailman, use the --with-mail-gid=mailman switch; + this will be the default if you configured Mailman after adding the + mailman owner. Because the owner of the aliases.db file is mailman, + Postfix will execute Mailman's wrapper program as uid and gid + mailman. + + That's it! One caveat: when you add or remove a list, the aliases.db + file will updated, but it will not automatically run postfix reload. + This is because you need to be root to run this and suid-root scripts + are not secure. The only effect of this is that it will take about a + minute for Postfix to notice the change to the aliases.db file and + update its tables. + + 6.1.2 Virtual domains + + Postfix 2.0 supports ``virtual alias domains'', essentially what used + to be called ``Postfix-style virtual domains'' in earlier Postfix + versions. To make virtual alias domains work with Mailman, you need to + do some setup in both Postfix and Mailman. Mailman will write all + virtual alias mappings to a file called, by default, + /usr/local/mailman/data/virtual-mailman. It will also use postmap to + create the virtual-mailman.db file that Postfix will actually use. + + First, you need to set up the Postfix virtual alias domains as + described in the Postfix documentation (see Postfix's virtual(5) + manpage). Note that it's your responsibility to include the + virtual-alias.domain anything line as described manpage; Mailman will + not include this line in virtual-mailman. You are highly encouraged to + make sure your virtual alias domains are working properly before + integrating with Mailman. + + Next, add a path to Postfix's virtual_alias_maps variable, pointing to + the virtual-mailman file, e.g.: + + virtual_alias_maps = <your normal virtual alias files>, + hash:/usr/local/mailman/data/virtual-mailman + + assuming you've installed Mailman in the default location. If you're + using an older version of Postfix which doesn't have the + virtual_alias_maps variable, use the virtual_maps variable instead. + + Next, in your mm_cfg.py file, you will want to set the variable + POSTFIX_STYLE_VIRTUAL_DOMAINS to the list of virtual domains that + Mailman should update. This may not be all of the virtual alias domains + that your Postfix installation supports! The values in this list will + be matched against the host_name attribute of mailing lists objects, + and must be an exact match. + + Here's an example. Say that Postfix is configured to handle the virtual + domains dom1.ain, dom2.ain, and dom3.ain, and further that in your + main.cf file you've got the following settings: + + myhostname = mail.dom1.ain + mydomain = dom1.ain + mydestination = $myhostname, localhost.$mydomain + virtual_alias_maps = + hash:/some/path/to/virtual-dom1, + hash:/some/path/to/virtual-dom2, + hash:/some/path/to/virtual-dom2 + + If in your virtual-dom1 file, you've got the following lines: + + dom1.ain IGNORE + @dom1.ain @mail.dom1.ain + + this tells Postfix to deliver anything addressed to dom1.ain to the + same mailbox at mail.dom1.com, its default destination. + + In this case you would not include dom1.ain in + POSTFIX_STYLE_VIRTUAL_DOMAINS because otherwise Mailman will write + entries for mailing lists in the dom1.ain domain as + + mylist@dom1.ain mylist + mylist-request@dom1.ain mylist-request + # and so on... + + The more specific entries trump your more general entries, thus + breaking the delivery of any dom1.ain mailing list. + + However, you would include dom2.ain and dom3.ain in mm_cfg.py: + + POSTFIX_STYLE_VIRTUAL_DOMAINS = ['dom2.ain', 'dom3.ain'] + + Now, any list that Mailman creates in either of those two domains, will + have the correct entries written to + /usr/local/mailman/data/virtual-mailman. + + As above with the data/aliases* files, you want to make sure that both + data/virtual-mailman and data/virtual-mailman.db are user and group + owned by mailman. + + 6.1.3 An alternative approach + + Fil fil@rezo.net has an alternative approach based on virtual maps and + regular expressions, as described at: + + * (French) http://listes.rezo.net/comment.php + * (English) http://listes.rezo.net/how.php + + This is a good (and simpler) alternative if you don't mind exposing an + additional hostname in the domain part of the addresses people will use + to contact your list. I.e. if people should use mylist@lists.dom.ain + instead of mylist@dom.ain. + +6.2 Using the Exim mail server + + Note: This section is derived from Nigel Metheringham's ``HOWTO - Using + Exim and Mailman together'', which covers Mailman 2.0.x and Exim 3. It + has been updated to cover Mailman 2.1 and Exim 4. The original document + is here: http://www.exim.org/howto/mailman.html. + + There is no Mailman configuration needed other than the standard + options detailed in the Mailman install documentation. The Exim + configuration is transparent to Mailman. The user and group settings + for Mailman must match those in the config fragments given below. + + 6.2.1 Exim configuration + + The Exim configuration is built so that a list created within Mailman + automatically appears to Exim without the need for defining any + additional aliases. + + The drawback of this configuration is that it will work poorly on + systems supporting lists in several different mail domains. While + Mailman handles virtual domains, it does not yet support having two + distinct lists with the same name in different virtual domains, using + the same Mailman installation. This will eventually change. (But see + below for a variation on this scheme that should accommodate virtual + domains better.) + + The configuration file excerpts below are for use in an already + functional Exim configuration, which accepts mail for the domain in + which the list resides. If this domain is separate from the others + handled by your Exim configuration, then you'll need to: + + * add the list domain, ``my.list.domain'' to local_domains + * add a ``domains=my.list.domain'' option to the director (router) + for the list + * (optional) exclude that domain from your other directors (routers) + + Note: The instructions in this document should work with either Exim 3 + or Exim 4. In Exim 3, you must have a local_domains configuration + setting; in Exim 4, you most likely have a local_domains domainlist. If + you don't, you probably know what you're doing and can adjust + accordingly. Similarly, in Exim 4 the concept of ``directors'' has + disappeared - there are only routers now. So if you're using Exim 4, + whenever this document says ``director'', read ``router''. + + Whether you are using Exim 3 or Exim 4, you will need to add some + macros to the main section of your Exim config file. You will also need + to define one new transport. With Exim 3, you'll need to add a new + director; with Exim 4, a new router plays the same role. + + Finally, the configuration supplied here should allow co-habiting + Mailman 2.0 and 2.1 installations, with the proviso that you'll + probably want to use mm21 in place of mailman - e.g., MM21_HOME, + mm21_transport, etc. + + 6.2.2 Main configuration settings + + First, you need to add some macros to the top of your Exim config file. + These just make the director (router) and transport below a bit + cleaner. Obviously, you'll need to edit these based on how you + configured and installed Mailman. + + # Home dir for your Mailman installation -- aka Mailman's prefix + # directory. + MAILMAN_HOME=/usr/local/mailman + MAILMAN_WRAP=MAILMAN_HOME/mail/mailman + + # User and group for Mailman, should match your --with-mail-gid + # switch to Mailman's configure script. + MAILMAN_USER=mailman + MAILMAN_GROUP=mailman + + 6.2.3 Transport for Exim 3 + + Add this to the transports section of your Exim config file, i.e. + somewhere between the first and second ``end'' line: + + mailman_transport: + driver = pipe + command = MAILMAN_WRAP \ + '${if def:local_part_suffix \ + {${sg{$local_part_suffix}{-(\\w+)(\\+.*)?}{\$1}}} \ + {post}}' \ + $local_part + current_directory = MAILMAN_HOME + home_directory = MAILMAN_HOME + user = MAILMAN_USER + group = MAILMAN_GROUP + + 6.2.4 Director for Exim 3 + + If you're using Exim 3, you'll need to add the following director to + your config file (directors go between the second and third ``end'' + lines). Also, don't forget that order matters - e.g. you can make + Mailman lists take precedence over system aliases by putting this + director in front of your aliasfile director, or vice-versa. + + # Handle all addresses related to a list 'foo': the posting address. + # Automatically detects list existence by looking + # for lists/$local_part/config.pck under MAILMAN_HOME. + mailman_director: + driver = smartuser + require_files = MAILMAN_HOME/lists/$local_part/config.pck + suffix_optional + suffix = -bounces : -bounces+* : \ + -confirm+* : -join : -leave : \ + -owner : -request : -admin + transport = mailman_transport + + 6.2.5 Router for Exim 4 + + In Exim 4, there's no such thing as directors - you need to add a new + router instead. Also, the canonical order of the configuration file was + changed so routers come before transports, so the router for Exim 4 + comes first here. Put this router somewhere after the ``begin routers'' + line of your config file, and remember that order matters. + + mailman_router: + driver = accept + require_files = MAILMAN_HOME/lists/$local_part/config.pck + local_part_suffix_optional + local_part_suffix = -bounces : -bounces+* : \ + -confirm+* : -join : -leave : \ + -owner : -request : -admin + transport = mailman_transport + + 6.2.6 Transports for Exim 4 + + The transport for Exim 4 is the same as for Exim 3 (see 6.2; just copy + the transport given above to somewhere under the ``begin transports'' + line of your Exim config file. + + 6.2.7 Additional notes + + Exim should be configured to allow reasonable volume - e.g. don't set + max_recipients down to a silly value - and with normal degrees of + security - specifically, be sure to allow relaying from 127.0.0.1, but + pretty much nothing else. Parallel deliveries and other tweaks can also + be used if you like; experiment with your setup to see what works. + Delay warning messages should be switched off or configured to only + happen for non-list mail, unless you like receiving tons of mail when + some random host is down. + + 6.2.8 Problems + + * Mailman will send as many MAIL FROM/RCPT TO as it needs. It may + result in more than 10 or 100 messages sent in one connection, + which will exceed the default value of Exim's + smtp_accept_queue_per_connection value. This is bad because it will + cause Exim to switch into queue mode and severely delay delivery of + your list messages. The way to fix this is to set Mailman's + SMTP_MAX_SESSIONS_PER_CONNECTION (in $prefix/Mailman/mm_cfg.py) to + a smaller value than Exim's smtp_accept_queue_per_connection. + * Mailman should ignore Exim delay warning messages, even though Exim + should never send this to list messages. Mailman 2.1's general + bounce detection and VERP support should greatly improve the bounce + detector's hit rates. + * List existence is determined by the existence of a config.pck file + for a list. If you delete lists by foul means, be aware of this. + * If you are getting Exim or Mailman complaining about user ids when + you send mail to a list, check that the MAILMAN_USER and + MAILMAN_GROUP match those of Mailman itself (i.e. what were used in + the configure script). Also make sure you do not have aliases in + the main alias file for the list. + + 6.2.9 Receiver Verification + + Exim's receiver verification feature is very useful - it lets Exim + reject unrouteable addresses at SMTP time. However, this is most useful + for externally-originating mail that is addressed to mail in one of + your local domains. For Mailman list traffic, mail originates on your + server, and is addressed to random external domains that are not under + your control. Furthermore, each message is addressed to many recipients + - up to 500 if you use Mailman's default configuration and don't tweak + SMTP_MAX_RCPTS. + + Doing receiver verification on Mailman list traffic is a recipe for + trouble. In particular, Exim will attempt to route every recipient + addresses in outgoing Mailman list posts. Even though this requires + nothing more than a few DNS lookups for each address, it can still + introduce significant delays. Therefore, you should disable recipient + verification for Mailman traffic. + + Under Exim 3, put this in your main configuration section: + + receiver_verify_hosts = !127.0.0.1 + + Under Exim 4, this is probably already taken care of for you by the + default recipient verification ACL statement (in the RCPT TO ACL): + + accept domains = +local_domains + endpass + message = unknown user + verify = recipient + + which only does recipient verification on addresses in your domain. + (That's not exactly the same as doing recipient verification only on + messages coming from non-127.0.0.1 hosts, but it should do the trick + for Mailman.) + + 6.2.10 SMTP Callback + + Exim's SMTP callback feature is an even more powerful way to detect + bogus sender addresses than normal sender verification. Unfortunately, + lots of servers send bounce messages with a bogus address in the + header, and there are plenty that send bounces with bogus envelope + senders (even though they're supposed to just use an empty envelope + sender for bounces). + + In order to ensure that Mailman can disable/remove bouncing addresses, + you generally want to receive bounces for Mailman lists, even if those + bounces are themselves not bounceable. Thus, you might want to disable + SMTP callback on bounce messages. + + With Exim 4, you can accomplish this using something like the following + in your RCPT TO ACL: + + # Accept bounces to lists even if callbacks or other checks would fail + warn message = X-WhitelistedRCPT-nohdrfromcallback: Yes + condition = \ + ${if and {{match{$local_part}{(.*)-bounces\+.*}} \ + {exists {MAILMAN_HOME/lists/$1/config.pck}}} \ + {yes}{no}} + {yes}{no}} + + accept condition = \ + ${if and {{match{$local_part}{(.*)-bounces\+.*}} \ + {exists {MAILMAN_HOME/lists/$1/config.pck}}} \ + {yes}{no}} + {yes}{no}} + + # Now, check sender address with SMTP callback. + deny !verify = sender/callout=90s + + If you also do SMTP callbacks on header addresses, you'll want + something like this in your DATA ACL: + + deny !condition = $header_X-WhitelistedRCPT-nohdrfromcallback: + !verify = header_sender/callout=90s + + 6.2.11 Doing VERP with Exim and Mailman + + VERP will send one email, with a separate envelope sender (return + path), for each of your subscribers - read the information in + $prefix/Mailman/Defaults.py for the options that start with VERP. In a + nutshell, all you need to do to enable VERP with Exim is to add these + lines to $prefix/Mailman/mm_cfg.py: + + VERP_PASSWORD_REMINDERS = Yes + VERP_PERSONALIZED_DELIVERIES = Yes + VERP_DELIVERY_INTERVAL = Yes + VERP_CONFIRMATIONS = Yes + + (The director (router) above is smart enough to deal with VERP + bounces.) + + 6.2.12 Virtual Domains + + One approach to handling virtual domains is to use a separate Mailman + installation for each virtual domain. Currently, this is the only way + to have lists with the same name in different virtual domains handled + by the same machine. + + In this case, the MAILMAN_HOME and MAILMAN_WRAP macros are useless - + you can remove them. Change your director (router) to something like + this: + + require_files = /virtual/${domain}/mailman/lists/${lc:$local_part}/config.pck + + and change your transport like this: + + command = /virtual/${domain}/mailman/mail/mailman \ + ${if def:local_part_suffix \ + {${sg{$local_part_suffix}{-(\\w+)(\\+.*)?}{\$1}}} + {post}} \ + $local_part + current_directory = /virtual/${domain}/mailman + home_directory = /virtual/${domain}/mailman + + 6.2.13 List Verification + + This is how a set of address tests for the Exim lists look on a working + system. The list in question is quixote-users@mems-exchange.org, and + these commands were run on the mems-exchange.org mail server ("% " + indicates the Unix shell prompt): + + % exim -bt quixote-users + quixote-users@mems-exchange.org + router = mailman_main_router, transport = mailman_transport + + % exim -bt quixote-users-request + quixote-users-request@mems-exchange.org + router = mailman_router, transport = mailman_transport + + % exim -bt quixote-users-bounces + quixote-users-bounces@mems-exchange.org + router = mailman_router, transport = mailman_transport + + % exim -bt quixote-users-bounces+luser=example.com + quixote-users-bounces+luser=example.com@mems-exchange.org + router = mailman_router, transport = mailman_transport + + If your exim -bt output looks something like this, that's a start: at + least it means Exim will pass the right messages to the right Mailman + commands. It by no means guarantees that your Exim/Mailman installation + is functioning perfectly, though! + + 6.2.14 Document History + + Originally written by Nigel Metheringham postmaster@exim.org. Updated + by Marc Merlin marc_soft@merlins.org for Mailman 2.1, Exim 4. + Overhauled/reformatted/clarified/simplified by Greg Ward + gward@python.net. + +6.3 Using the Sendmail mail server + + Warning: You may be tempted to set the DELIVERY_MODULE configuration + variable in mm_cfg.py to 'Sendmail' when using the Sendmail mail + server. Don't. The Sendmail.py module is misnamed - it's really a + command line based message handoff scheme as opposed to the SMTP scheme + used in SMTPDirect.py (the default). Sendmail.py has known security + holes and is provided as a proof-of-concept only^4. If you are having + problems using SMTPDirect.py fix those instead of using Sendmail.py, or + you may open your system up to security exploits. + + 6.3.1 Sendmail ``smrsh'' compatibility + + Many newer versions of Sendmail come with a restricted execution + utility called ``smrsh'', which limits the executables that Sendmail + will allow to be used as mail programs. You need to explicitly allow + Mailman's wrapper program to be used with smrsh or Mailman will not + work. If mail is not getting delivered to Mailman's wrapper program and + you're getting an ``operating system error'' in your mail syslog, this + could be your problem. + + One good way of enabling this is: + + * Find out where your Sendmail executes its smrsh wrapper + % grep smrsh /etc/mail/sendmail.cf + + * Figure out where smrsh expects symlinks for allowable mail + programs. At the very beginning of the following output you will + see a full path to some directory, e.g. /var/adm/sm.bin or similar: + % strings $path_to_smrsh | less + + * cd into /var/adm/sm.bin, or where ever it happens to reside on your + system - alternatives include /etc/smrsh, /var/smrsh and + /usr/local/smrsh. + % cd /var/adm/sm.bin + + * Create a symbolic link to Mailman's wrapper program: + % ln -s /usr/local/mailman/mail/mailman mailman + + 6.3.2 Integrating Sendmail and Mailman + + David Champion has contributed a recipe for more closely integrating + Sendmail and Mailman, such that Sendmail will automatically recognize + and deliver to new mailing lists as they are created, without having to + manually edit alias tables. + + In the contrib directory of Mailman's source distribution, you will + find four files: + + * mm-handler.readme - an explanation of how to set everything up + * mm-handler - the mail delivery agent (MDA) + * mailman.mc - a toy configuration file sample + * virtusertable - a sample for RFC 2142 address exceptions + + 6.3.3 Performance notes + + One of the surest performance killers for Sendmail users is when + Sendmail is configured to synchronously verify the recipient's host via + DNS. If it does this for messages posted to it from Mailman, you will + get horrible performance. Since Mailman usually connects via localhost + (i.e. 127.0.0.1) to the SMTP port of Sendmail, you should be sure to + configure Sendmail to not do DNS verification synchronously for + localhost connections. + +6.4 Using the Qmail mail server + + There are some issues that users of the qmail mail transport agent have + encountered. None of the core maintainers use qmail, so all of this + information has been contributed by the Mailman user community, + especially Martin Preishuber and Christian Tismer, with notes by Balazs + Nagy (BN) and Norbert Bollow (NB). + + * You might need to set the mail-gid user to either qmail, mailman, + or nofiles by using the --with-mail-gid configure option. + BN: it highly depends on your mail storing policy. For example if + you use the simple ~alias/.qmail-* files, you can use `id -g + alias`. But if you use /var/qmail/users, the specified mail gid can + be used. + If you are going to be directing virtual domains directly to the + mailman user (using ``virtualdomains'' on a list-only domain, for + example), you will have to use --with-mail-gid=gid of mailman + user's group. This is incompatible with having list aliases in + ~alias, unless that alias simply forwards to mailman-listname*. + * If there is a user mailman on your system, the alias mailman-owner + will work only in ~mailman. You have to do a touch .qmail-owner in + ~mailman directory to create this alias. + NB: An alternative, IMHO better solution is to chown root ~mailman, + that will stop qmail from considering mailman to be a user to whom + mail can be delivered. (See ``man 8 qmail-getpw''.) + * In a related issue, if you have any users with the same name as one + of your mailing lists, you will have problems if list names contain + "-" in them. Putting .qmail redirections into the user's home + directory doesn't work because the Mailman wrappers will not get + spawned with the proper GID. The solution is to put the following + lines in the /var/qmail/users/assign file: + +zope-:alias:112:11:/var/qmail/alias:-:zope-: + . + + where in this case the listname is e.g. zope-users. + NB: Alternatively, you could host the lists on a virtual domain, + and use the /var/qmail/control/virtualdomains file to put the + mailman user in charge of this virtual domain. + * BN:If inbound messages are delivered by another user than mailman, + it's necessary to allow it to access ~mailman. Be sure that + ~mailman has group writing access and setgid bit is set. Then put + the delivering user to mailman group, and you can deny access to + ~mailman to others. Be sure that you can do the same with the WWW + service. + By the way the best thing is to make a virtual mail server to + handle all of the mail. NB: E.g. make an additional "A" DNS record + for the virtual mailserver pointing to your IP address, add the + line lists.kva.hu:mailman to /var/qmail/control/virtualdomains and + a lists.kva.hu line to /var/qmail/control/rcpthosts file. Don't + forget to HUP the qmail-send after modifying ``virtualdomains''. + Then every mail to lists.kva.hu will arrive to mail.kva.hu's + mailman user. + Then make your aliases: + .qmail => mailman@...'s letters + .qmail-owner => mailman-owner's letters + + For list aliases, you can either create them manually: + .qmail-list => posts to the 'list' list + .qmail-list-admin => posts to the 'list's owner + .qmail-list-request => requests to 'list' + etc + + or for automatic list alias handling (when using the lists.kva.hu + virtual as above), see contrib/qmail-to-mailman.py in the Mailman + source distribution. Modify the ~mailman/.qmail-default to include: + |preline /path/to/python /path/to/qmail-to-mailman.py + + and new lists will automatically be picked up. + * You have to make sure that the localhost can relay. If you start + qmail via inetd and tcpenv, you need some line the following in + your /etc/hosts.allow file: + tcp-env: 127. 10.205.200. : setenv RELAYCLIENT + + where 10.205.200. is your IP address block. If you use tcpserver, + then you need something like the following in your /etc/tcp.smtp + file: + 10.205.200.:allow,RELAYCLIENT="" + 127.:allow,RELAYCLIENT="" + + * BN: Bigger /var/qmail/control/concurrencyremote values work better + sending outbound messages, within reason. Unless you know your + system can handle it (many if not most cannot) this should not be + set to a value greater than 120. + * More information about setting up qmail and relaying can be found + in the qmail documentation. + + BN: Last but not least, here's a little script to generate aliases to + your lists (if for some reason you can/will not have them automatically + picked up using contrib/qmail-to-mailman.py): + + This script is for the Mailman 2.0 series: + +#!/bin/sh +if [ $# = 1 ]; then + i=$1 + echo Making links to $i in the current directory... + echo "|preline /home/mailman/mail/mailman post $i" > .qmail-$i + echo "|preline /home/mailman/mail/mailman mailowner $i" > .qmail-$i-admin + echo "|preline /home/mailman/mail/mailman mailowner $i" > .qmail-$i-owner + echo "|preline /home/mailman/mail/mailman mailowner $i" > .qmail-owner-$i + echo "|preline /home/mailman/mail/mailman mailcmd $i" > .qmail-$i-request +fi + + Note: This is for a new Mailman 2.1 installation.

If you are interested in + VERP there are two options. The first option is to allow Mailman to do + the VERP formatting. To activate this, uncomment that line and add the + following lines to your mm_cfg.py file: + + VERP_FORMAT = '%(bounces)s-+%(mailbox)s=%(host)s' + VERP_REGEXP = r'^(?P<bounces>.*?)-\+(?P<mailbox>[^=]+)=(?P<host>[^@]+)@.*$' + + The second option is a patch on SourceForge located at: + + http://sourceforge.net/tracker/?func=detail&atid=300103&aid=645513&grou + p_id=103 + + This patch currently needs more testing and might best be suitable for + developers or people well familiar with qmail. Having said that, this + patch is the more qmail-friendly approach resulting in large + performance gains. + + 6.4.2 Virtual mail server + + As mentioned in the 6.4 section for a virtual mail server, a patch + under testing is located at: + + http://sf.net/tracker/index.php?func=detail&aid=621257&group_id=103&ati + d=300103 + + Again, this patch is for people familiar with their qmail installation. + + 6.4.3 More information + + You might be interested in some information on modifying footers that + Norbert Bollow has written about Mailman and qmail, available here: + + http://mailman.cis.to/qmail-verh/ + + 7 Review your site defaults + + Mailman has a large number of site-wide configuration options which you + should now review and change according to your needs. Some of the + options control how Mailman interacts with your environment, and other + options select defaults for newly created lists^5. There are system + tuning parameters and integration options. + + The full set of site-wide defaults lives in the + $prefix/Mailman/Defaults.py file, however you should never modify this + file! Instead, change the mm_cfg.py file in that same directory. You + only need to add values to mm_cfg.py that are different than the + defaults in Defaults.py, and future Mailman upgrades are guaranteed + never to touch your mm_cfg.py file. + + The Defaults.py file is documented extensively, so the options are not + described here. The Defaults.py and mm_cfg.py are both Python files so + valid Python syntax must be maintained or your Mailman installation + will break. + + Note: Do not change the HOME_DIR or MAILMAN_DIR variables. These are + set automatically by the configure script, and you will break your + Mailman installation by if you change these. + + You should make any changes to mm_cfg.py using the account you + installed Mailman under in the 14 section. + + 8 Create a site-wide mailing list + + After you have completed the integration of Mailman and your mail + server, you need to create a ``site-wide'' mailing list. This is the + one that password reminders will appear to come from, and it is + required for proper Mailman operation. Usually this should be a list + called mailman, but if you need to change this, be sure to change the + MAILMAN_SITE_LIST variable in mm_cfg.py. You can create the site list + with this command, following the prompts: + + % bin/newlist mailman + + Now configure your site list. There is a convenient template for a + generic site list in the installation directory, under + data/sitelist.cfg which can help you with this. You should review the + configuration options in the template, but note that any options not + named in the sitelist.cfg file won't be changed. + + The template can be applied to your site list by running: + + % bin/config_list -i data/sitelist.cfg mailman + + After applying the sitelist.cfg options, be sure you review the site + list's configuration via the admin pages. + + You should also subscribe yourself to the site list. + + 9 Set up cron + + Several Mailman features occur on a regular schedule, so you must set + up cron to run the right programs at the right time^6. + + If your version of crontab supports the -u option, you must be root to + do this next step. Add $prefix/cron/crontab.in as a crontab entry by + executing these commands: + + % cd $prefix/cron + % crontab -u mailman crontab.in + + If you used the --with-username option, use that user name instead of + mailman for the -u argument value. If your crontab does not support the + -u option, try these commands: + + % cd $prefix/cron + % su - mailman + % crontab crontab.in + + 10 Start the Mailman qrunner + + Mailman depends on a process called the ``qrunner'' to delivery all + email messages it sees. You must start the qrunner by executing the + following command from the $prefix directory: + + % bin/mailmanctl start + + You probably want to start Mailman every time you reboot your system. + Exactly how to do this depends on your operating system. If your OS + supports the chkconfig command (e.g. RedHat and Mandrake Linuxes) you + can do the following (as root, from the Mailman install directory): + + % cp scripts/mailman /etc/init.d/mailman + % chkconfig --add mailman + + Note that /etc/init.d may be /etc/rc.d/init.d on some systems. + + On Gentoo Linux, you can do the following: + + % cp scripts/mailman /etc/init.d/mailman + % rc-update add mailman default + + On Debian, you probably want to use: + + % update-rc.d mailman defaults + + For Unixes that don't support chkconfig, you might try the following + set of commands: + + % cp scripts/mailman /etc/init.d/mailman + % cp misc/mailman /etc/init.d + % cd /etc/rc.d/rc0.d + % ln -s ../init.d/mailman K12mailman + % cd ../rc1.d + % ln -s ../init.d/mailman K12mailman + % cd ../rc2.d + % ln -s ../init.d/mailman S98mailman + % cd ../rc3.d + % ln -s ../init.d/mailman S98mailman + % cd ../rc4.d + % ln -s ../init.d/mailman S98mailman + % cd ../rc5.d + % ln -s ../init.d/mailman S98mailman + % cd ../rc6.d + % ln -s ../init.d/mailman K12mailman + + 11 Check the hostname settings + + You should check the values for DEFAULT_EMAIL_HOST and DEFAULT_URL_HOST + in Defaults.py. Make any necessary changes in the mm_cfg.py file, not + in the Defaults.py file. If you change either of these two values, + you'll want to add the following afterwards in the mm_cfg.py file: + + add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST) + + You will want to run the bin/fix_url.py to change the domain of any + existing lists. + + 12 Create the site password + + There are two site-wide passwords that you can create from the command + line, using the bin/mmsitepass script. The first is the ``site + password'' which can be used anywhere a password is required in the + system. The site password will get you into the administration page for + any list, and it can be used to log in as any user. Think root for a + Unix system, so pick this password wisely! + + The second password is a site-wide ``list creator'' password. You can + use this to delegate the ability to create new mailing lists without + providing all the privileges of the site password. Of course, the owner + of the site password can also create new mailing lists, but the list + creator password is limited to just that special role. + + To set the site password, use this command: + + % $prefix/bin/mmsitepass <your-site-password> + + To set the list creator password, use this command: + + % $prefix/bin/mmsitepass -c <list-creator-password> + + It is okay not to set a list creator password, but you probably do want + a site password. + + 13 Create your first mailing list + + For more detailed information about using Mailman, including creating + and configuring mailing lists, see the Mailman List Adminstration + Manual. These instructions provide a quick guide to creating your first + mailing list via the web interface: + + * Start by visiting the url http://my.dom.ain/mailman/create. + * Fill out the form as described in the on-screen instructions, and + in the ``List creator's password'' field, type the password you + entered in section 7. Type your own email address for the ``Initial + list owner address'', and select ``Yes'' to notify the list + administrator. + * Click on the ``Create List'' button. + * Check your email for a message from Mailman informing you that your + new mailing list was created. + * Now visit the list's administration page, either by following the + link on the confirmation web page or clicking on the link from the + email Mailman just sent you. Typically the url will be something + like http://my.dom.ain/mailman/admin/mylist. + * Type in the list's password and click on ``Let me in...'' + * Click on ``Membership Management'' and then on ``Mass + Subscription''. + * Enter your email address in the big text field, and click on + ``Submit Your Changes''. + * Now go to your email and send a message to mylist@my.dom.ain. + Within a minute or two you should see your message reflected back + to you via Mailman. + + Congratulations! You've just set up and tested your first Mailman + mailing list. If you had any problems along the way, please see the 14 + section. + + 14 Troubleshooting + + If you encounter problems with running Mailman, first check the + question and answer section below. If your problem is not covered + there, check the online help, including the FAQ and the interactive FAQ + wizard. + + Also check for errors in your syslog files, your mail and web server + log files and in Mailman's $prefix/logs/error file. If you're still + having problems, you should send a message to the + mailman-users@python.org mailing list^7; see + http://mail.python.org/mailman/listinfo/mailman-users for more + information. + + Be sure to including information on your operating system, which + version of Python you're using, and which version of Mailman you're + installing. + + Here is a list of some common questions and answers: + + * Problem: All Mailman web pages give a 404 File not found error. + Solution: Your web server has not been set up properly for handling + Mailman's CGI programs. Make sure you have: + 1. configured the web server to give permissions to + $prefix/cgi-bin + 2. restarted the web server properly. + Consult your web server's documentation for instructions on how to + do check these issues. + * Problem: All Mailman web pages give an "Internal Server Error". + Solution: The likely problem is that you are using the wrong user + or group for the CGI scripts. Check your web server's log files. If + you see a line like + Attempt to exec script with invalid gid 51, expected 99 + + you will need to reinstall Mailman, specifying the proper CGI group + id, as described in the section. + * Problem: I send mail to the list, and get back mail saying the list + is not found! + Solution: You probably didn't add the necessary aliases to the + system alias database, or you didn't properly integrate Mailman + with your mail server. Perhaps you didn't update the alias + database, or your system requires you to run newaliases explicitly. + Refer to your server specific instructions in the 6 section. + * Problem: I send mail to the list, and get back mail saying, + ``unknown mailer error''. + Solution: The likely problem is that you are using the wrong user + or group id for the mail wrappers. Check your mail server's log + files; if you see a line like + Attempt to exec script with invalid gid 51, expected 99 + + you will need to reinstall Mailman, specifying the proper mail + group id as described in the section. + * Problem: I use Postfix as my mail server and the mail wrapper + programs are logging complaints about the wrong GID. + Solution: Make sure the $prefix/data/aliases.db file is user owned + by mailman (or whatever user name you used in the configure + command). If this file is not user owned by mailman, Postfix will + not run the mail programs as the correct user. + * Problem: I use Sendmail as my mail server, and when I send mail to + the list, I get back mail saying, ``sh: mailman not available for + sendmail programs''. + Solution: Your system uses the Sendmail restricted shell (smrsh). + You need to configure smrsh by creating a symbolic link from the + mail wrapper ($prefix/mail/mailman) to the directory identifying + executables allowed to run under smrsh. + Some common names for this directory are /var/admin/sm.bin, + /usr/admin/sm.bin or /etc/smrsh. + Note that on Debian Linux, the system makes /usr/lib/sm.bin, which + is wrong, you will need to create the directory /usr/admin/sm.bin + and add the link there. Note further any aliases newaliases spits + out will need to be adjusted to point to the secure link to the + wrapper. + * Problem: I messed up when I called configure. How do I clean things + up and re-install? + Solution: + % make clean + % ./configure --with-the-right-options + % make install + + 15 Platform and operating system notes + + Generally, Mailman runs on any POSIX-based system, such as Solaris, the + various BSD variants, Linux systems, MacOSX, and other generic Unix + systems. It doesn't run on Windows. For the most part, the generic + instructions given in this document should be sufficient to get Mailman + working on any supported platform. Some operating systems have + additional recommended installation or configuration instructions. + +15.1 GNU/Linux issues + + Linux seems to be the most popular platform for running Mailman. Here + are some hints on getting Mailman to run on Linux: + + * If you are getting errors with hard link creations and/or you are + using a special secure kernel (securelinux/openwall/grsecurity), + see the file contrib/README.check_perms_grsecurity in the Mailman + source distribution. + Note that if you are using Linux Mandrake in secure mode, you are + probably concerned by this. + * Apparently Mandrake 9.0 changed the permissions on gcc, so if you + build as the mailman user, you need to be sure mailman is in the + cctools group. + * If you installed Python from your Linux distribution's package + manager (e.g. .rpms for Redhat-derived systems or .deb for Debian), + you must install the ``development'' package of Python, or you may + not get everything you need. + For example, using Python 2.2 on Debian, you will need to install + the python2.2-dev package. On Redhat, you probably need the + python2-devel package. + If you install Python from source, you should be fine. + One symptom of this problem, although for unknown reasons, is that + you might get an error such as this during your install: + Traceback (most recent call last): + File "bin/update", line 44, in ? + import paths + ImportError: No module named paths + make: *** [update] Error 1 + + If this happens, install the Python development package and try + configure and make install again. Or install the latest version of + Python from source, available from http://www.python.org. + This problem can manifest itself in other Linux distributions in + different ways, although usually it appears as ImportErrors. + +15.2 BSD issues + + Vivek Khera writes that some BSDs do nightly security scans for setuid + file changes. setgid directories also come up on the scan when they + change. Also, the setgid bit is not necessary on BSD systems because + group ownership is automatically inherited on files created in + directories. On other Unixes, this only happens when the directory has + the setgid bit turned on. + + To install without turning on the setgid bit on directories, simply + pass in the DIRSETGID variable to make, after you've run configure: + + % make DIRSETGID=: install + + This disables the chmod g+s command on installed directories. + +15.3 MacOSX issues + + Many people run Mailman on MacOSX. Here are some pointers that have + been collected on getting Mailman to run on MacOSX. + + * Jaguar (MacOSX 10.2) comes with Python 2.2. While this isn't the + very latest stable version of Python, it ought to be sufficient to + run Mailman 2.1. + * David B. O'Donnell has a web page describing his configuration of + Mailman 2.0.13 and Postfix on MacOSX Server. + http://www.afp548.com/Articles/mail/python-mailman.html + * Kathleen Webb posted her experiences in getting Mailman running on + Jaguar using Sendmail. + http://mail.python.org/pipermail/mailman-users/2002-October/022944. + html + * Panther server (MacOSX 10.3) comes with Mailman; Your operating + system should contain documentation that will help you, and Apple + has a tech document about a problem you might encounter running + Mailman on Mac OS X Server 10.3: + http://docs.info.apple.com/article.html?artnum=107889 + + Terry Allen provides the following detailed instructions on running + Mailman on the 'client' version of OSX, or in earlier versions of OSX: + + Mac OSX 10.3 and onwards has the basics for a successful Mailman + installation. Users of earlier versions of Mac OSX contains Sendmail + and those users should look at the Sendmail installation section for + tips. You should follow the basic installation steps as described + earlier in this manual, substituting as appropriate, the steps outlined + in this section. + + By default, Mac OSX 10.3 'client' version does not have a fully + functional version of Postfix. Setting up a working MTA such as Postfix + is beyond the scope of this guide and you should refer to + http://www.postfix.org for tips on getting Postfix running. An easy way + to set Postfix up is to install and run Postfix Enabler, a stand-alone + tool for configuring Postfix on Mac OSX, available from + http://www.roadstead.com/weblog/Tutorials/PostfixEnabler.html. + + Likewise, Mac OSX 'client' version from 10.1 onwards includes a working + Apache webserver. This is switched on using the System Preferences + control panel under the 'Sharing tab'. A useful tool for configuring + the Apache on Mac OSX is Webmin, which can be obtained from + http://www.webmin.com. + + Webmin can also perform configuration for other system tasks, including + Postfix, adding jobs to your crontab, adding user and groups, plus + adding startup and shutdown jobs. + + In a stock installation of OSX, the requirement for Mailman is to have + Python installed. Python is not installed by default, so it is advised + that you install the developer's tools package, which may have been + provided with your system. It can also be downloaded from the Apple + developer site at http://connect.apple.com. Not only is the developer + tools package an essential requirement for installing Mailman, but it + will come in handy at a later date should you need other tools. The + developer's tools are also know by the name XCode tools. + + As a minimum, the Python version should be 2.2, but 2.3 is recommended. + + If you wish to add a user and group using the command line in OSX + instead of via Webmin or another GUI interface, open your terminal + application and follow the commands as indicated below - do not type + the comments following the "#" since they are just notes: + +sudo tcsh +niutil -create / /users/mailman +niutil -createprop / /users/mailman name mailman +# Note that xxx is a free user ID number on your system +niutil -createprop / /users/mailman uid xxx +niutil -createprop / /users/mailman home /usr/local/mailman +mkdir -p /usr/local/mailman +niutil -createprop / /users/mailman shell /bin/tcsh +passwd mailman +# To prevent malicious hacking, supply a secure password here +niutil -create / /groups/mailman +niutil -createprop / /groups/mailman name mailman +# Note that xxx is a free group ID number on your system +niutil -createprop / /groups/mailman gid xxx +niutil -createprop / /groups/mailman passwd '*' +niutil -createprop / /groups/mailman users 'mailman' +chown mailman:mailman /usr/local/mailman +cd /usr/local/mailman +chmod a+rx,g+ws . +exit +su mailman + + For setting up Apache on OSX to handle Mailman, the steps are almost + identical and the configuration file on a stock Mac OSX Client version + is stored in the nearly standard location of /etc/httpd/httpd.conf. + + The AFP548.com site has a time-saving automated startup item creator + for Mailman, which can be found at + http://www.afp548.com/Software/MailmanStartup.tar.gz + + To install it, copy it into your /Library/StartupItems directory. As + the root or superuser, from the terminal, enter the following: + +gunzip MailmanStartup.tar.gz +tar xvf MailmanStartup.tar + + It will create the startup item for you so that when you reboot, + Mailman will start up. + + About this document ... + + GNU Mailman - Installation Manual, December 5, 2007, Release 2.1 + + This document was generated using the LaTeX2HTML translator. + + LaTeX2HTML is Copyright © 1993, 1994, 1995, 1996, 1997, Nikos Drakos, + Computer Based Learning Unit, University of Leeds, and Copyright © + 1997, 1998, Ross Moore, Mathematics Department, Macquarie University, + Sydney. + + The application of LaTeX2HTML to the Python documentation has been + heavily tailored by Fred L.
