| #pragma page-filename DOC/versions/10715240 Mailman can be configured to automatically [[http://www.list.org/mailman-install/node13.html|generate list aliases for Postfix]], and this process can also be hijacked to [[DOC/Integrating Mailman with Sendmail - Method 2|generate aliases automatically for sendmail]]. Mailman can also be additionally configured to automatically [[http://www.list.org/mailman-install/postfix-virtual.html|generate virtual alias mappings for postfix]]. Some people find these features insufficient as they want to have Mailman lists in a domain which is a postfix virtual_mailbox_domain. This can be done by using transport_maps rather than virtual_alias_maps for the Mailman addresses in that domain. The following is a way to automate that. {{{#!wiki caution The following is based on email exchanges and is believed to work, but the author has not personally tested it. }}} 1. Put the list domain(s) in POSTFIX_STYLE_VIRTUAL_DOMAINS in mm_cfg.py just as if they were going to be virtual_alias_domains. 1. Do not put the domains in Postfix virtual_alias_domains, and do not put hash:/path/to/data/virtual_mailman in virtual_alias_maps. 1. Create /path/to/data/virtual_to_transport with the following content {{{ #!/bin/sh sed -r -e 's/(^[^#][^ \t]+[ \t]+).+$/\1local/' $1 \ > /path/to/data/transport-mailman /usr/sbin/postmap /path/to/data/transport-mailman }}} 1. Then {{{ chgrp mailman /path/to/data/virtual_to_transport chmod 750 /path/to/data/virtual_to_transport }}} If your Mailman group is not 'mailman', put the actual group in the chgrp command. 1. Put {{{ POSTFIX_MAP_CMD = '/path/to/data/virtual_to_transport' }}} in mm_cfg.py 1. Run Mailman's bin/genaliases. This will create/update the following files in /path/to/data/: aliases aliases.db virtual-mailman transport-mailman transport-mailman.db Make sure transport-mailman and transport-mailman.db have permissions like aliases and aliases.db. In particular, transport-mailman.db must be readable by Postfix. From now on, these files will be maintained automatically by Mailman as lists are created and deleted. 1. Add "hash:/path/to/data/transport-mailman" to transport_maps in main.cf. 1. Reload Postfix to pick up the main.cf changes. |
