Well, UCE is UCE... and it's not a "gray area". The problem you've raised
is false-positives...
Here's what we do:
1. All inbound items go first to our EmailScrub server where they are
checked for viruses and trojans. Positives are bounced back to the sender
with a notice to the intended recipient... virus-free email is passed on.
2. Next they are 'razor'ed by spamassassin... and given a numeric score.
Clearly 0 is clean, 25 is spam. We currently add {SPAM?} to the subject line
of any that score 6.6 or higher. Members of this forum may benefit from
looking at spamassassin and the tests they run and values assigned.
3. All items are passed to Imail where individual customers or IT guys for
larger sites maintain rules.ima. We recommend the use of TRASH folders.
What I'd like to do is participate in a forum to share ideas for tuning
rules.ima. I'm not worried about Spammers sueing me or about my customers
not getting important investment newsletters because we don't delete Email
and our customers maintain their own rules.ima (with our help).
But you have me wondering if someone tried to send me an Email notice to
sell Cisco when it was $54 and I didn't get it and if I could find out who
deleted that Email I can sue them for the $30 grand I've lost.
Mike
