Hmm, so when a list only contains other lists as members, those will use postfix's local transport, but when the members are individuals (for final delivery), it uses virtual. Ok, that makes sense then.

Also the weirdness when a list member has their vacation enabled - they
get the original list message, but the vacation message gets stuck in
the queue with the error.

Another case of multiple messages to be handled by the local transport.

Ok, yeah, I think you've nailed it... the problem is when more than one message at a time is passed to postfix/local...

I'm thinking of trying to reinstalling (this is gentoo, so that will be
easy) first mailman, then postfix... I'll probably try that tomorrow if
no other solution presents itself.

If you reinstall Mailman without touching Postfix and that fixes this,
I'll be incredibly surprised.

I think you're right, I'll do postfix first.

All the evidence you've presented together with everything I know says
this is a Postfix issue, not a Mailman issue. If I knew Postfix as well
as I know Mailman, I could probably tell you how to fix this.

Wish I did... I did get a comment from Victor on the postfix list to check all of my aliases, so I ran newaliases but that didn't help. Is there anything else I can do to test the mailman aliases? Since the individual lists work - confirmed because I sent the mass email I've been trying to send since this happened to each individual list that is a member of the lists-all list, and those all worked fine.

I agree with you that this seems to be a postfix problem, but is it possible that some kind of corruption in a userb could cause these warnings? To recap, they are:

The first one from postfix/master only shows up rarely - 11 times since I got the system back up, and within 5 or 10 minutes (but usually with 5 or 10 seconds) of postfix being restarted:

postfix/master[6406]: warning: master_wakeup_timer_event: service tlsmgr(private/tlsmgr): Resource temporarily unavailable

Then these (only when I try to send to my lists-all list):

warning: connect to transport private/local: Resource temporarily unavailable warning: connect to transport private/retry: Resource temporarily unavailable

I do have backups of my mysql userdb, as well as all others (mailman aliases/dbs, etc), so I can replace any of these from backups if it will fix the problem.

Thanks again for your time and help Mark...
