I don't understand why you think SAV is a louse anti-forgery tool. It
forces spammers to have to find real email addresses to forge.
So here's a little thought experiment for you.
As you know more and more spam is sent by botnets from compromised
machines. Those bots know a range of valid addresses because they're
pulling them out of addressbooks on the local machines (they're also
sending to those same addresses btw).
So - let's say you don't use SAV. You accept the message not knowing
that it's from a fake address. Then you have to spam filter it. If if
fails, it creates a bounce.
No. You do your spam filtering during the SMTP session, using a milter
or something similar. If it scores as spam, then you reject it during SMTP.
So, no, it doesn't create a bounce. Only an idiot would bounce a
message for being spam.
