Bouncing Specific Addresses With Mailer Table Setup

I have the setup (sendmail/MailScanner/SpamAssassin/ClamAV/Mailwatch 
mail hub in front of a CommunigatePro mail server). I use SMF-SAV 
milter to do the user verification. It uses the mailer table and then 
asks Communicate if that user exists before accepting the email and if 
that users doesn't exist, it rejects with a "550 5.1.1 Sorry, no 
mailbox here with that name" error. It works really well. It can also 
do Sender Address Verification where it looks up the mx record for the 
sending email address domain and then goes and asks that mail server 
if the sending username really exists, if not it rejects the email. 
Either of those functions can be disabled and there is the ability to 
enter Whitelists.

Hope this helps.
