Subject: Spam with PGP

The answer to SPAM IMHO is filtering on the client side.  Our server filter
gets 80%+ of it but I still got 50+ SPAMs a day.  Since going to PopFile
proxy filter on my laptop (awsome & free @ sourceforge) I get maybe one a
week. It's based on Bayesian Theorum.  Not bad for a 15th Century monk ;)

Well, this reminds us that a spam filter, although definitely a good
thing, it's not the definitive solution, just like a firewall IMHO.
You can't bet too much on a purely automatic solution.
Anyway, again like firewalls, I'm not so pessimistic: completely
filtering out what you don't want could be, OK, impossible but filtering
out almost all, is what we really need.
