It's not the bounces I want to stop. It's the fact that I have bounces
to mailservers that don't exist, won't accept connections, are not where
the message originated from. The mechanics of the mail process I can
deal with, it's the deceptive practices of spammers.

I don't know if a bounce is valid until I try to send it. Either the
bounce message is accepted or not. If accepted, chances are it was a
valid bounce. If not, then it is to late, I've already processed the

If I understand what you and most others are suggesting, I should move
my user validation from the toasters to the MailScanners. I thought of
this, and I think it could be done since my vpopmail is using MySQL
auth. However that would not stop the bounces.
