This says it was successfully delivered to Postfix.

And Postfix is saying it sent the mail to gmail-smtp-in.l.google.com
for michaelmcandrew at gmail.com and received confirmation (250 2.0.0 OK
1147349502 c28si796656nfb) from that server.

It definitely seems to be outside of Mailman and even your local
Postfix. Since it only affects posts, it seems it must have something
to do specifically with the sender, headers or body of the post itself.

One thing that may be different is the envelope sender if you are using
Mailman virtual hosts. In this case, (un-VERPed) list mail will have
an envelope sender of listname-bounces at list.domain, but some
administrative messages may be sent by
mailman-bounces at DEFAULT_EMAIL_HOST. See
<http://mail.python.org/pipermail/mailman-users/2006-April/050706.html>
which is not exactly relevant to your situation, but may be
interesting.
