Hello, We are seeing an increasing number of error messages (wrong address, virus, etc...) coming back to somebody who has not sent the incriminated message in the first place. In most cases, the address is usurpated by some virus, using the address book and/or the messages on the infected machine. When the mail server or the antivirus software sends back an error message to the apparent sender, it comes into the legitimate owner mailbox, who wanders why he receives this message. It wouldn't be a big problem if it concerned a small amount of messages, but sometimes, it happens to be hundreds of error messages, saturating a mailbox in a few hours time. Does anyone has some ideas about how to discard this kind of messages ONLY, without discarding legitime MAILER-DAEMON messages in the mean time ? Is there any way to distinguish a legitimate error message from an usurpated address one when people use various SMTP servers for sending mail, often different from the one receiving their mail ? -- Didier Lebrun Le bourg - 81140 - Vaour (France) tél: 05.63.53.73.41 (AM et soirée) mailto:[email protected] (MIME, ISO latin 1) http://didier.quartier-rural.org/
