This should happen automatically, when an MTA uses the DNSBL feature. I don't know about sendmail, but with postfix, all you need to do is to add the following lines to the smtpd_recipient_restrictions field in /usr/local/etc/postfix/main.cf: smtpd_recipient_restrictions = # . more restrictions here . reject_rbl_client bl.spamcop.net, reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client list.dsbl.org, reject_rbl_client dnsbl.njabl.org, reject_rbl_client relays.ordb.org, reject_rbl_client opm.blitzed.org, reject_rbl_client dnsbl.sorbs.net, # . more restrictions here . The descriptive text, if provided by the blacklist as a TXT DNS record, is then always included in the bounce message.

DNSBL - including descriptive text in sendmail error message
I am configuring a mail server to make use of the DNS-based black lists supplied by spamhaus.org, and have run into a bit of a snag. I'm running sendmail 8.12.11, and have successfully configured the 'dnsbl' feature to reject mail from hosts in the black lists, but spamhaus.org has requested that MTA error messages contain the descriptive text corresponding to the blacklisted host (e.g. "http://www.spamhaus.org/SBL/sbl.lasso?query=SBL14030";). I've checked sendmail docs for information on how to do this, and come up with nothing. I've also looked for the information on the spamhaus site itself, but to no avail. Likewise for Google searches. The black lists themselves are quite helpful, and so I would like to be in compliance with spamhaus' request. Any clues would be much appreciated. BTW, I hope it's not inappropriate to have posted this to both -isp and -questions. Please let me know if I should not have done so.
