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.
