Corbett, i've been hoping to find a minute to look into this behavior - 
i may be able to get to it later today.  In the meanwhile, please check
for any relevant entries in your ~mailman/logs/errors log file, and if
there are any, send copies to me.

And let me see if i understand correctly - you say that /var/log/maillog
indicates that your sendmail sent the messages to the users, but the
users never see them?  This would suggest that the messages *really*
foul up the receiving side - and that brings one possibilty to mind. 

There is a known bug in some recent versions of sendmail (8.8.x for some
x, and 8.9.0) such that the sendmail will core dump when attempting to
deliver mailman's (or any 8-bit encoded) Mime-format digests in certain
(somewhat uncommon) circumstances.  The question then is, were the
messages that never appeared in the users mailbox Mime digests?  And if
not, could you construct a repeatable test that at least reduces the
likelihood that the problem is on the receiving ends?  For that matter,
might you happen to be running sendmail 8.8.x or 8.9.0?  Your sendmail
may be getting so far as negotiating the delivery and then failing
partway through...

With the info available currently it's hard to know what of mailman to
investigate on this end, since mailman evidently got the messages to
your MTA.
