This is a job for your MTA. SA doesn't know about SMTP-level
operations. You need to configure your MTA to track invalid RCPT TO
commands, and then perform the host-based rejections as necessary.
Unknown users will be rejected in the first place, so I don't really
know what it is you are intending to do.
