I don't doubt that. Their generated UBE is often commercial in nature, too,
because they usually carry an advertising link along with the spew.

I have enough regex filters, thank you. I don't plan to encourage yet more
UBE by standardizing it -- think [YOU-]CAN-SPAM for antivirus apps. I
should not have to waste the bandwidth cost at DATA for yet more UBE.

Actually, I get about ten to twenty times as much virus blowback as I get
spam from trojan-zombie boxes.
That's because the virus blowback comes from otherwise "reputable" MTAs,
whereas the spam comes form zombies that are often already blacklisted, or
are in known dynamic pools that are blocked here. Thus the zombies get
blocked long before DATA, but the "reputable" MTAs sending the backscatter
don't get caught so early.
