It would. Exactly. because Spamassassin doesn't care if only the _first_ host in the relay chain was a DUL or if any other host was a DUL. If I send my mail from my dialup host to my ISP and it relays it, I will still get scored by SpamAssassin. And that is the problem. SA also lacks a system to not score IPs from users that connect e.g. via SMTP AUTH (and are therefore usually legit users) but that is another issue. > Users on DULs shouldn't even run their own smtp server since they can't > even keep their systems patched and maintain sufficient virus defs. I agree. But users on DUL _must_ be able to send mail to their ISPs mail servers without getting scores from SA users. And that is currently not the case. > As for your example, all the other guys are labeling it as open proxy/open > relay.

The spammer noticed he was being blocked, he hung up, redialed, got a new IP and *bang* somebody else got the blocked IP. Long term open relay/proxy lists DO NOT MAKE SENSE with dial up IPs. So dialup IPs should not get listed in those lists - at least not for longer than 24h, which is the maximum connection time every DSL provider I know allows before forcing hang-up.
