On the one hand, it's reasonable not to DUL your own dialup pool if
you're ready to respond and act on abuse complaints relating to them and
have a trustworthy user base, and on the other hand if you don't want to
deal with complaints at all you should filter tcp/25 from your dialup
pool to the Internet; registering with DUL and not filtering is a wierd
sort of compromise in between.
This does raise the question of some sort of crowbar functionality in
one's qmail relay servers, such that you're actually accomplishing
anything by forcing them to relay rather than going straight out from the
dialup pool; you'd need to ID your user, probably by consulting your
RADIUS server, track RCPTs/user/hour, share that data among multiple
redundant relay servers, and be able to shunt the user's outbound mail
into a holding tank when it goes over the volume threshold and alert a
human admin.
