	That is a great idea.  I can probably do a procmail
recipe to look for all the work-related sources and pass them
through, gif's and all.  I guess I trained the bogofilter data
base well because false positives haven't been a problem.  It's
usually been the procmail rules that spamified good messages
because they tend to be simplistic and sure enough, something in
a good message fits the criteria.

	Our Exchange gateways are running a ProofPoint spam
filter which tags messages that go through it as to their
probability of being spam and I already have procmail rules to
look for the headers which have been right on target.

	Again, thanks for the suggestions.
