Ho hum ... Convenient to blame a temp net error for the first dns related error I've seen in ages, right after testing your new dns resolving code. Coincidence maybe. This is going nowhere - end thread. :-(
Question: how many other MTAs do their own DNS lookups ? Do they use the OS resolver setting ? What is the benefit of Xmail doing the dns resolution entirely by itself?

I had no problems in sending to that domain, and in general I had no problems whatsoever so far with it. You didn't try to resend to that domain, did you? You probably hit a temporary network problem, you saw the message XMail generated, and you posted to the mailing list. Why it is more rare that you see this using a 'named' resolver? Because 'named' caches *everything*, so it is easier that temporary network problems end up being hidden by its caching. - 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]
