If you look inside some slog file, you'll see "End of socket stream data" errors, that means that the connection has been dropped while XMail was trying to read data from the remote SMTP server. If this data happened to be the ack response to the SMTP DATA command, XMail will *obviously* consider the delivery as failed, while the remote server, if not performing checks correctly, might consider the message as received. This smells a lot like either broken MTAs ar very broken firewalls in the middle path. - 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]
