It is hardly Rici's fault if your IP address is listed in real-time
black holes.  (See )

I suspect our mail system would think twice about accepting mail from
you, too.  I suggest you lobby the RBLs in question to reduce the amount
of time dynamically allocated IPs stay on the list.

(Personally, I love the fact that DSL/Cable dynamic IPs are mostly
listed - it greatly reduces the amount of spam I receive from people who
don't know how to secure their Windows box.)

On another note, heuristic spam filters are becoming less and less
effective - in a way, they'll never win the battle, as the spammers are
always one step ahead.  Statistical systems are proving to be much more
effective now they've had a chance to develop.

(We use SpamAssassin, and apart from it using an enormous amount of CPU
time and bandwidth, it only catches about 90% of spams, which while
sounds good, that's still hundreds getting through. :-/ )
