[Mailman-Users] virtual domain setup with postfix

[David Newman]

MM 2.1.9, Postfix 2.3.5, cyrus-imap 2.3.7, all on FreeBSD 6.1 installed from ports

Postfix already handles mail for multiple virtual domains defined in a MySQL database. I believe virtual domain setup is OK, as individual users have been sending and receiving mail for some time.

Having problems with Mailman, though. I've read these instructions many times:

http://www.list.org/mailman-install/postfix-virtual.html

Besides doing what's listed there, I also defined a virtual mailbox for a new "pctest" list (without that, mail sent to pctest at virt1.tld bounces).

However, MM never distributes the mail to list subscribers. /var/log/maillog says each message is sent to pctest at virt1.tld; however, the only files in /usr/local/mailman/logs that change are smtp and subscribe (and then only when list members are added).

Basically, postfix delivers message to pctest at virt1.tld but nothing happens after that.

Thanks in advance for clues on fixing this.
