 You are correct, this was a typo in main.cf, and has been changed.

/var/lib/mailman/data/virtual-mailman has the line:
MailingList at lists.domain3.com              MailingList

and /var/lib/mailman/data/aliases contains the line
MailingList:             "|/var/lib/mailman/mail/mailman post MailingList"

You are correct, the alias_maps line in /etc/postfix/main.cf does not reference hash:/var/lib/mailman/data/aliases I changed it to be:
alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases

and now it appears to work.

I AM using Debian, but in setting up mailman, the FAQ makes postfix_to_mailman.py out to be a bad idea, so I abandoned it and tried to do things "The Right Way™". The alias_map was probably the core problem.  Thanks for the help!
