Network connectivity issues during a DNS query should at most cause a delay in sending the mail, but the mail should eventually get through without user intervention.
I'm still concerned that your fall back to "A" after MX timeout could cause a permanent delivery failure (trying to send to the host pointed to by the "A" record, potentially hitting an SMTP server that would refuse the delivery) when the failure should only be temporary (can't get any results from the domain's DNS servers due to a network failure somewhere while trying to lookup the MX record). Admittedly, this would be a _very_ small window of opportunity, but still possible if Xmail handles this as you suggest. - 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]
