This is easily worked around. Define another "smtpd" service in
master.cf on an alternate port with an override for
smtpd_recipient_restrictions and use that port for Mailman delivery, but
that may not be needed anyway. See below.

OK. So the bulk of the mail was delivered to Postfix in a bit over 5
minutes. That seem quite reasonable. I clearly misunderstood what you
ment when you said mail was still going out after days.

Some of these may be retries of temp fails from Postfix (anything in
smtp-failure?) and some may be unrelated.

Actually 5 minutes and 9 seconds or 309 seconds by the logs above.

The welcome message is queued in Mailman's virgin queue and processed
asynchronously by VirginRunner which moves it to Mailman's out queue
where it is processes (again asynchronously by OutgoingRunner).

Yes, it is 'academic' but a deeper understanding of the processes
involved can't hurt. I'm compulsive (often too much so) about answering
every outstanding question, even if they are only my own questions.
