Since folks *do* forward spam in practice (even I have replied to
well-crafted social-engineered messages and included the original
message to ask the presumed sender if they did, in fact, send the
message), the use of -u is ill-advised.

The problem is later when one does a full retraining on the corpus.

My workaround is to delete spammy messages so that they aren't later
misclassified as ham.
