Leaving aside from the question of if virus-infected DSNs are UBE and thus "spam" or not... Todd Vierling wrote: If you want to notify someone about a filtered malware instance, notify thethis is the crux of the matter. When your filtering system determines that the message contains a virus, the filter KNOWS (or should know, and with a high degree of certainty) the message is unwanted and the "sender" is forged. Your recipient/customer doesn't want to see the message OR the DSN. So why send either on to someone else?! It is a reprehensible practice to send the notice off to the "sender" by claiming that an RFC says this is what you should do with a generic DSN. It is NOT a good practice, it IS network abuse. It is reprehensible to knowingly or "innocently" design software to do this, or to use software that does this by default unless you make very certain that you have disabled this "feature" and that it STAYS disabled whenever you upgrade or otherwise change the software configuration. All of this is crystal clear without needlessly arguing or trying to determine if DSNs of virus infected email are "spam" or not. It was sent to your recipient/customer and if they don't want it then treat it the same way you treat all other email they don't want (spam filtering). jc
