Thanks, I'll keep this information around for future reference!  In the meantime, the queue was automatically retried and the changes I made to postfix configuration were correct, so the mail was delivered just fine!

(Mailman seems to deliver outgoing list messages to the local SMTP server via "::1".  I was expecting  I wasn't expecting ipv6!  ["Nobody expects ipv6!"])   :)
