What am I missing,as a commercial email verification service what are they trying to validate?
Likely someone/somewhere submitted that^ email to a list, on your ... ahem ... "behalf". Now, some client is using that list -- whether they originated it or bought it -- and is paying 'briteverify' to "clean" their lists. So they send to your server, use your resource (aka, the postfix accept/reject/bounce/etc) to check if it's valid, and "profit". Personally, I consider email-verification services parasites -- and manage my server accordingly. Postfix provides a _great_ set of tools to reject what you wish at numerous transaction stages. Add to that option to firewall-off IP addresses -- and enjoy the silence. Not a choice/action everyone is willing/able to make.
