Someone at mail-abuse.org came up with the idea of creating a list to enable
ISP's to "blacklist" their pools of dialups.
Apparently they assumed that the "stuff it all to a smarthost" is the correct
way to do SMTP email. Possibly because it's the only thing the likes of
Netscape and IE can handle. Even though this approach isn't, AFAIK, even
mentioned, let alone advised in any RFC.
The actual RFC complient way is to do an MX DNS lookup and attempt to
connect in the order of the preference field. Which the DUL will quite
happily break.
IIRC somewhere in the docs there are instructions on how to hack qmail
to send through a specific relay machine. Alternativly complain to your
ISP or change ISP's.
