It doesn't matter what the notifications look like. There is no reason that my SMTP server should be subject to more than TEN THOUSAND of these damned things every day, which I must receive all the way through the DATA phase in order to block. That's the problem: just like other forms of UBE, virus-worm warnings (to forged addresses) *do not scale*. I don't care what kind of duck the UBE looks like. Content is irrelevant. It still looks, walks, and quacks like a UBE duck.
There is a solution you can implement now that gets rid of these tens of thousands of virus and abuse laden DSNs you see every day before the data phase. It could be seen as less than altruistic to bounce content of suspected malware, so perhaps one should not expect standardization of DSN content either. There are many languages to deal with as well. With BATV, the slogan could be a quote from Socrates "Know thyself." With BATV, you should stop blaming others for _your_ inability to deal with a DSN problem. Calling DSNs UBE is not a solution, although traffic from AV applications seems to be approaching that definition. If it has a null return-path, that is all you should need. -Doug
