Davide, I can see you are adamant that xmail did not use the www.optusnet.com.au for delivery and I agree with you, however, I see that the path followed to get the point of reporting www.optusnet.com.au is....
1. decipher domain part of TO address (optusnet.com.au) 2. get NS records for optusnet.com.au 3. get MX records for optusnet.com.au 4. some error occurred, so get A record for optusnet.com.au. (what the error was is not important here) 5. get PTR record for the IP we are going to send to: 211.29.132.105 (The A record) 6. attempt to send email & fail 7. send a bounce email to postmaster (and sender) reporting the name obtained from the PTR lookup. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This is what xmail has done forever, and is not a problem, as long as you know the name reported is the PTR, rather than the domain part of the TO address. I think it is just fine as it is. SO.... Getting back to the real issue at hand... Why would a VERY large ISP (optusnet.com.au) be broken. It certainly is not broken now when DIGs are done. The only difference is that one NS that wasn't responding - it now is. And you say that xmail tries all NS records until it gets valid results or all NS are exhausted, so one NS not responding should not be a problem. Unfortunately the reason I switched to SMARTDNSHOST years ago was due to the reliability of xmail's DNS lookup routines. I use 'named' as a caching DNS server and point xmail to it and have had very little problem caused by lookup failure since. Within one day of trying NO SMARTDNSHOST on 1.25pre06, I had undeliverable emails. I have since re-enabled SMARTDNSHOST and again I have no problems (the user has resent the emails successfully).

There is no way "www.optusnet.com.au" could have been shawn in there is it wasn't coming from an MX response. - Davide - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
