Claudio,
I have patched qmail-smtpd.c to include the IP address of the culprit in
the error message. It has cut down on escalations from our support team
greatly as well as their time spent researching RBL problems.
The patch may be an ugly hack, but it works by changing about three
lines of code. It would be great if the main qmail-ldap patch included
this or something like it.
The SMTP error response looks something like this:
553 sorry, your mailserver [1.1.1.1] is rejected by
http://www.spamhaus.org/xbl for having a compromized proxy.
