upgrade of postfix broke Mailman
On a box running Sid, I recently apt-get dist-upgrade'd Postfix. Prior
to the upgrade I had Postfix running smoothly with a virtual setup based
on MySQL tables. Additionally, I had Mailman integrated into
After the upgrade, I first found that virtual users no longer received
email. I fixed this quickly by adding to main.cf:
local_recipient_maps = $virtual_mailbox_maps
with $virtual_mailbox_maps representing all of my users with email
But in adding this, I found that attempts to deliver to Mailman no
longer got through (got a 550 error saying "User unknown in local
So I removed it again and presto, Mailman delivers properly.
So with 'local_recipient_maps' I can deliver to my virtual users but not
to Mailman. And without 'local_recipient_maps' I cannot deliver to
virtual users but can deliver to Mailman.
How do I reconcile this?
In the upgrade the dynamicmaps.cf file was changed, and 'proxy' was
added to master.cf. On the surface I don't see how these changes could
have screwed me up, but perhaps I missing something.
I've got a thick book on Postfix, but it hasn't helped on this one. And
I've gooogled til my eyes have started spinning.
Any help would sure be appreciated.
