DSBL http://dsbl.org/main is good at the front door for blocks. After
that we SpamAssassin tag it and let the end user decide. SA uses the
SURBL and SPF and other things you wouldn't want to outright block on
in consideration without removing the ability to bypass (whitelist) the
filter.

Warnings? Only the usual, be very picky with blacklists. There is a big
difference between even confirmed and unconfirmed dsbl.
