If you are using sendmail+spamassassin as a filtering gateway in front
of some backend server (EG exchange), then I'd suggest using a sendmail
'milter' daemon rather than your spamc configuration (such as
miltrassassin).
This has the advantage of being more fault-tolerant (what happens with
your config if something breaks and causes "spamc" to choke on each
message?)
You can configure it to do a SMTP-reject of a spam message rather than
just silently deleting it.
That has the major advantage that the sender is notified of the
rejection (assuming that the sending system is legitimate).
Thus if something unexpected happens and you mark a legitmate message
as spam there's hope for discovery and repair rather than things just
mysteriously dissapearing. ;(
