Aside: If you'd post from your subscribed address, you'd avoid
moderation delay and possible rejection of your post.
In list posts, unless the list is anonymous, the Message-ID: is the
Message-ID of the incoming message. Mailman's internally generated
messages and anonymized posts have a Message-ID of the form
Message-ID: mailman.sssss.ttttt.ppppp.listname at hostname
where sssss is a sequence #
ttttt is a time returned by Python's time.time()
ppppp is the PID of the generating process

I note that all this mail is routed through tummms.chboston.org. What do
the MTA logs on that server show?
Note that the <201303300400.r2U402Tx030401 at healthmap.chip.org> message
id is not a Mailman generated message id. It was either generated by the
process that originated the mail or it was added by healthmap.chip.org
because the message passed through that MTA without a Message-ID:.
