No, I meant that blocking based on the *source* being an open relay or
open proxy is acceptable, since there's no excuse for having such a
system.

Which I agree makes a lot of the spam reductions options (subscription
required, or some of the extremist options like DUL blocking)
unacceptable. The xbl.spamhaus.org appears to be based on fairly
legitimate criteria, though: your site has to be a source of spam that
is somehow magically fingerprinted as coming from an open proxy or open
relay. That seems unlikely to affect someone struggling to get their
Debian mailserver working, since the configuration scripts of both exim
and postfix make it fairly difficult to set up such a system. And since
it would presumably bounce back to the correct person (rather than being
dropped later), at least they would *know* they weren't getting through,
and could be directed to fix it.
