that's what dynamic IP rbl's are for. Since they can't be tracked, they must
relay through some static addresses (most often their ISP's mail server),
usually with SMTP authentication (although your ISP may allow you relaying
without auth, others will not, and may not even receive mail from you).

not the dsl users, but the users with dynamically assigned IP addresses.
I do not care whether they are dial-up, ISDN, DSL, cable or wtf. If they do
not have their own IP (and thus can't effectively be blacklisted), they must
auth.

you should switch to zen.spamhaus.org, sbl-xbl is going to die.
I use (not only) sorbs njabl (combined.njabl.org) and spamhaus, together
they are very effective.
