Same difference to me, you get blocked. My servers are busy enough
as it is (just as an example, one incoming SMTP server out of 4 with
one client has consistent 80 connections per second, an average 500
connections active at any given tine, the majority, over 80%, bounces
or SAV checks). So guess what? I'm going to block those servers
until they smarten up.
The reason you get so many bounces is that your servers are SAV
hostile. If someone spoofs your domain then you're going to get SAV
connection if you allow it or bounce connections if you don't. And the
number of bounces is going to be a lot higher than the SAV requests
because spammers like domains where the recipient host gives no
information about if the account is valid or not.
Uhhh, no. We don't bounce. Anyone who bounces is an asshat. We reject
551 at the smtp level for spam above a certain score and for user unknown.
We aren't anti-SAV per say, we are anti-usernamechecking, we will return
a "User Unknown" after 5 similar unsuccessful requests during the same
smtp connection.
Think logically about it.
