Ken & company:
More info...to correct myself earlier on the sendmail logs (and to be precise), I sent a test message (no MIME, just a 1 sentence text message) to one of our small lists (it's the list shown at http://www2.acm.jhu.edu/mailman/listinfo/tm).
Sending out that message generated the below entries in /var/log/maillog:
Aug 3 14:04:36 chimera sendmail[15085]: OAA15085: from=<cklempay@chimera.acm.jhu.edu>, size=657, class=0, pri=30657, nrcpts=1, msgid=<Pine.LNX.3.96.98080314042 5.15083A-100000@chimera.acm.jhu.edu>, proto=SMTP, relay=cklempay@localhost Aug 3 14:04:36 chimera sendmail[15086]: OAA15086: clone OAA15085, owner=tm-admin Aug 3 14:04:37 chimera sendmail[15086]: OAA15086: to=|"/home/mailman/mail/wrapper post tm", delay=00:00:01, xdelay=00:00:01, mailer=prog, stat=Sent
As for ~mailman/logs/errors...there is no such file in that directory (so no recorded errors, I guess).
I'm running sendmail 8.9.1. All of the previous messages I tried were simple text messages (with whole bodies of things like "Holler if ya hear me").
