The RNDS check happens "inline" and the message is not even accepted if the resolution does not succeed. The message will never enter the queue, and this happen with every mail server that uses such kind of feature. And it is in that way that must work. - 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]
