This is rather +similar to qmail-to-mailman.py with a few changes to the code to accommodate +differences between the the two MTAs and a number of changes to the +instructions in the comments. This script has worked flawlessly for me for +over 5 years, so it's been well tested. + +Note, of course, that a line will need to be added to configure.in (and +configure, implicitly, via autoconf) to copy the file and replace tokens used +in the attached script with actual paths. + +Courier is actively supported and development on it is ongoing, whereas qmail +is unsupported and largely depreciated for use in new mail server +installations. diff --git a/contrib/courier-to-mailman.py b/contrib/courier-to-mailman.py new file mode 100644 index 00000000..922401fb --- /dev/null +++ b/contrib/courier-to-mailman.py @@ -0,0 +1,125 @@ +#! /usr/bin/python + +# Configuration variables - Change these for your site if necessary. +# +MailmanHome = "@prefix@"; # Mailman home directory. +MailmanVar = "@VAR_PREFIX@"; # Mailman directory for mutable data. +MailmanOwner = "postmaster@localhost"; # Postmaster and abuse mail recepient. +# +# End of configuration variables. + +# courier-to-mailman.py +# +# Interface mailman to a Courier virtual domain.

It catches all mail to any address +# at a virtual domain not otherwise handled by an explicit account or a +# .courier file. It looks at the recepient for each mail message not +# otherwise handled and decides if the mail is addressed to a valid list or +# not, and bounces the message with a helpful suggestion if it's not +# addressed to a list. It decides if it is a posting, a list command, or +# mail to the list administrator by checking for the various address tags as +# defined in manual Mailman list creation output (~mailman/bin/newlist). It +# will recognize a list as soon as the list is created. Above and beyond +# setting up a proper locally-hosted domain in Courier (the use of webadmin +# is highly recommended!), no other configuration should be required. This +# program recognizes mail to postmaster, mailman-owner, abuse, +# mailer-daemon, root, and owner, and routes those mails to MailmanOwner as +# defined in the configuration variables, above. +# +# INSTALLATION: +# +# Install this file as @prefix@/bin/courier-to-mailman.py +# +# To configure a virtual domain to connect to mailman, create these files: +# +# <domain_home>/alias/.courier-listname +# ... containing ... +# |/usr/bin/preline @prefix@/bin/courier-to-mailman.py +# +# Symlink <domain_home>/alias/.courier-listname-default to this file +# +# "listname" is the name of your list. +# +# Paths must, of course, be set correctly for the Courier and Mailman +# installations on your system. +# +# Note: "preline" is a Courier program which ensures a Unix "From " header +# is on the message.
