Depends upon your mail transfer agent (MTA). Postfix, for example, has a variety of classes of errors that will (potentially) generate messages to postmaster, including "bounce" and "double-bounce". I have both turned on, because MOST bounces are spammers trying to hit spam traps... But, you would only want "double-bounce", which would only notify you if a bounce message bounced itself. -- Jeff Brenton President, Engineered Software Products, Inc http://espi.com Questionable web page: http://dididahdahdidit.com Liberalism grants you the freedom to advocate any idea*. * Please see http://www.dididahdahdidit.com/except.php for a current list of exceptions
