If not, it sends the appropriate error code (syntax error in address - see RFC 822, date missing etc...). There IS a window where the remote mailer could time out, but to date I have never seen this actually happen - remember, it is NOT trying to deliver the message, just verify the headers and queue it for delivery..... -ed cetron cetron@utah-cs.arpa
