I use amavisd-new which has support for listing viruses/worms that fake the sender's email address. Unfortunatelly the list is external to the actual virus scanner and has to be updated manually. This is a major problem, since the administrators are often (an with good reason) not responsive enought with the rapid floods like the one we saw recently. > it should not send out notification messages unless the administrator has > been warned that these notification messages may not reach the intended > recipient and has still enabled this feature. I would say that a virus scanner SHOULD NOT send notifications unless it has informations on the reliability of the sender's e-mail address. > 1.2.)

They could be formatted with a message/delivery-status part but the problem wouldn't exist at all if all the notifications are sent to the real infected recipient. Bye. -- Daniele Orlandi
