Ok, but what does xmail when all the servers in the smtprelay list return a 5xx code ? Retry later ? Same think 'retry later' when, in normal delivery (no smtprelay use) all the mx servers for the destination domain return a 5xx errors ? If yes, 'retry later', IMOO, it's not the good action to take as all reject with a fatal error. So, as xmail works now, if all return a 5xx, xmail will wait until all retries are done on all relays/mx before sending a ndr ? IMOO, in theses cases (all smtpgateways/mx return a 5xx) xmail should stop processing the mail and return an ndr to the sender. No ? (I will read rfc 2821 again to try to find the options availables on 5xx and multiple relays/mx cases in an unique retry cycle) Francis - 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]
