6.1.2 Virtual domains

From 3a258ad5cdd98c5705af6c02ba91993b3d382adc Mon Sep 17 00:00:00 2001 From: Barry Warsaw Date: Wed, 5 Dec 2007 17:23:41 -0500 Subject: Because the admin directory is no longer included, the www directory isn't either, and that's where the generated docs used to live. So now, make this directory include the generated docs, removing the old IPC7 and LISA-98 directories, and the .tex source files. These latter are moved to the admin repository. --- doc/mailman-install/postfix-virtual.html | 197 +++++++++++++++++++++++++++++++ 1 file changed, 197 insertions(+) create mode 100644 doc/mailman-install/postfix-virtual.html (limited to 'doc/mailman-install/postfix-virtual.html') diff --git a/doc/mailman-install/postfix-virtual.html b/doc/mailman-install/postfix-virtual.html new file mode 100644 index 00000000..4191fe11 --- /dev/null +++ b/doc/mailman-install/postfix-virtual.html @@ -0,0 +1,197 @@ + + + + + + + + + + + + + +6.1.2 Virtual domains + + + + + +

+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. + +
