Greetings all,

I thought I would put this out here as an offering, both to show what is
working for me and to leave myself open for feedback on how to improve
things.  I still hear complaints about receiving spam, but I imagine that
will always be the case no matter how I tweak the system.

These statistics are for two of my servers (thank you DLAnalyzer): one does
only relay mail (via Smarter Mail 3.x) for MS Exchange servers (inbound and
outbound) and the other does only POP mail (I-Mail 2006.1)

I delete at a weight of 20, and rewrite the subject at 10.  If I read the
statistics correctly, then out of 433,849 messages inspected, 327,466 were
immediately discarded, 47,981 remaining messages had the subject line
rewritten leaving 58,402 messages delivered to my users unmolested.

I do a lot more tests (83 total) but those were the top hitters.

Thanks for your time and feedback.
