It's practically impossible to blacklist user/host behind dynamic IP, unless
blacklisting them all. You can never know who really is behind the IP,
because that can change every few minutes.

Actually NJABL does provide 'dynablock' list but it's obsolete and was
passed to spamhaus (included in PBL). SORBS and MAPS have also their own
dynamic IP lists, the one in SORBS comes from the same source
(dynablock.easynet.nl iirc) but contains more IPs and seems to be better
maintained.

Such IP's are thus not designed to send mail directly to recipients - users
have to send mail through mailserver with static IP that can autenticate
them. They can't even receive mail, unless running kind of dyndns service,
but there can be problems with it...
