Yes, if you have defeated the security features of your mail server either accidentally or on purpose, but that is not what is happening in this case. There appears to be a recurrance (or mutation) of a virus we have seen before. The mail is not originating on your server. Your domain is being spoofed by the infected computer(s). The forged mail probably would not escape detection by a knowledgeable human, but it is good enough to fool some autoresponders and mail tossers, which is why you get the bounces. -- Lars Eighner http://www.larseighner.com/index.html 8800 N IH35 APT 1191 AUSTIN TX 78753-5266
