Jason, When was the last time you got a spam from [EMAIL PROTECTED] When was the last time you got a spam from [EMAIL PROTECTED] Only spaking from personal experience, but the number of spam messages sent from a non-existant domain is tiny.

Having said that, I think what Verisign did was dumb. ------------ Walden H Leverich III President Tech Software (516) 627-3800 x11 (208) 692-3308 eFax [EMAIL PROTECTED] http://www.TechSoftInc.com Quiquid latine dictum sit altum viditur.

This has potentially enormous ramifications. For one thing, this effectively breaks reverse-DNS lookups that anti-spam applications use to verify sending domains as being valid. Come on now, Verisign is masking the difference between a valid domain and NXDOMAIN for all protocols, all users, and all software. Doesn't anyone here have an opinion?
