BATV: <http://en.wikipedia.org/wiki/Bounce_Address_Tag_Validation> The Ironport solution uses this although they don't call it that. It works really well, though be sure you have the latest release of AsyncOS 5.5 or 6.1 due to a recently fixed bug. Note that BATV can aggravate issues caused by receivers who've implemented abusive anti-spam measures like SAV callbacks or challenge-response. ~JasonG -- ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
