Package: mailman
Version: 1:2.1.11-11
Severity: wishlist
Tags: patch
Hello,
I think the most beautiful way to use Mailman with Postfix is to dedicate it a
domain, and to use the specific transport to relay mail to it. But… as Postfix
does not know the valid addresses, messages to invalid recipients are treated
with bounces, that result in backscatter mail.
I found a way to avoid such bounces, and rather make Postfix refuse the invalid
messages during the client SMTP connexion. Indeed, for alias-based
configurations, Mailman is able to generate an Postfix-style alias table. With
the dedicated transport, we do not need this table, but… it can be used as a
relay recipient map, to make Postfix know wich addresses are valid for the
relayed domain!
So, here is a small patch for postfix-to-mailman.py, that modifies the
integration instructions. Hope it may be useful.
Regards,
