That may be so, but I've had really bad experiences with blacklists. One
site I use has been repeatedly blacklisted by Spamcop. It seems that if
you're a small site it only takes *one* spam-like message being submitted
to Spamcop to get you listed, and the only recourse you have is to wait
and hope that eventually they automatically delist you. Every blacklist
I've seen seems to take this "too bad, sucks to be you" attitude towards
incorrect information in their lists. This has turned me off on the whole
approach. (Well, that and the way ORBS used to spam my postmaster account
with their tests.)
