Maybe user validation would block the most...
Here I've a strange postfix setup due previous mailsystems. I need to verify first internal postfix checks befor (rbl, greylist) and then check mail
validation, because I need to execute a (little, but heavy enought) script to check the mail validation. So I want to reduce to the maximum the
incoming mails befor this check.
Maybe a day I'll have all my email-system in postfix, I hope! :)
