MS4.28.6 on a minimally modified Qube

[Leland J. Steinke]

The server is running sendmail 8.10.2, f-prot 4.4.1, clamav 0.68-1, and
spamassassin 2.63.  It looks like any MIME messages cause a coredump in the
Explode routine. There is no error logged even with "Debug = yes"; MS just
stops.

This was supposed to be a quick, simple (pro bono) upgrade for a church
school's mail server.  Several hours later, it has turned into anything but.


Any ideas or suggestions?
Leland

ps:  "Nuke the qube" is not a viable short-term solution.  ;-)
