I had a similar problem recently which turned out to be a problem with
some changes I had made to the LDAP member adaptor (which I was using
for the list). The bug in my changes was such that there were some
circumstances in which the list thought it had no members -- if this
happened when the message was being processed, then Mailman would (of
course) send it to no one. However, the message did get included in
the list archive.

So that is one kind of possibility, though of course there are many
other reasons why this might happen.
