Sorry for dredging up a months-old thread, but I was searching for a similar answer myself. We implement the full gamut of "reject_unknown_sender_domain"-type checks, and therefore end up blocking mail from misconfigured sites whose IP addresses don't reverse-resolve back to valid hostnames, etc. Unfortunately, this means that certain legitimate-but-broken customers have trouble sending us email. I'd like to include a link in the "554" message, directing people to the " http://parabon.com/reverse-dns.html reverse-dns.html " explanation we have on our website, just as a first-line defense to provide their IT departments the requisite information to solve the problem. As Patrick mentioned, it would be nice to have, e.g.: unknown_address_reject_reason unknown_hostname_reject_reason unknown_client_reject_reason ... etc. to go along with: unknown_address_reject_code unknown_hostname_reject_code unknown_client_reject_code ... etc. I'm sure there are more important features than this seemingly simple request, but I just wanted to voice my own +1 vote for this "diagnostic enhancement". Thanks, all! :-D -- :- Dabe -- View this message in context: http://www.nabble.com/Configurable-replies-for-hardcoded-REJECTS--tp23096401p24928488.html Sent from the Postfix mailing list archive at Nabble.com.
