I'm new to Mailman and I wonder if there is a proper way to automatically add the addresses created in the virtual-mailman file (when a new list is created) to a list for the check_sender_access postfix restriction. For example, if I create the list "mailmantest", the following is added to the virtual-mailman file:

# STANZA START: mailmantest # CREATED: Wed Aug 26 11:32:36 2009 mailmantest@domain.tld              mailmantest mailmantest-admin@domain.tld        mailmantest-admin mailmantest-bounces@domain.tld      mailmantest-bounces mailmantest-confirm@domain.tld      mailmantest-confirm mailmantest-join@domain.tld         mailmantest-join mailmantest-leave@domain.tld        mailmantest-leave mailmantest-owner@domain.tld        mailmantest-owner mailmantest-request@domain.tld      mailmantest-request mailmantest-subscribe@domain.tld    mailmantest-subscribe mailmantest-unsubscribe@domain.tld  mailmantest-unsubscribe # STANZA END: mailmantest

In my Postfix main.cf file I have:

smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/lists_relay, reject

The /etc/postfix/lists_relay file is like this:

mailmantest@domain.tld OK mailmantest-admin@domain.tld OK mailmantest-bounces@domain.tld OK

And so on.

I'd like those entries in the /etc/postfix/lists_relay file to be created automatically after running "newlist mailmantest".

Assuming that your lists_relay is intended to whitelist outgoing messages from Mailman, the -bounces entry should be sufficient as all messages from Mailman are sent with envelope from SOMELIST-bounces or mailman-bounces except in one rare circumstance, notices of mailman-bounces bounces are sent with envelope from mailman-loop.

Well, we have whitelists for all the outbound mail, so does messages from Mailman. Anything not in a check_sender_access hash will be rejected. That's why I needed this.

I see two ways you can deal with this automatically.

If you are comfortable with Python, you could modify Mailman/MTA/Postfix.py to write a third files containing the information you want and call postmap to update the corresponding hash database.

Perhaps a simpler solution is to set POSTFIX_MAP_CMD which defaults to '/usr/sbin/postmap' to point instead to a shell script which does

/usr/bin/postmap $1

followed by a sed or whatever to create the file you want by editing the virtual-mailman file and finally by another postmap to update the hash db.

Thank you very much for your tips!
