forwarded emails

[Kevin Miller]

I figured that the forwarding would happen before MailScanner gets involved.  I.e., in their virtuserfile or whatever passes for that if not using sendmail.
I gotta wonder though why one needs to whitelist users on the same system.  Blacklisting a problem user might make sense, but I'm not sure what the actual application is here.  No matter though - to each their own...

I don't think so. MailScanner looks at the sender and recipient of the message as it arrives at the MTA. MailScanner knows nothing about the subsequent forward that might occur. It is not until the MTA attempts to deliver the mail to bill at domain.tld (after MailScanner has processed it) that it will find the .forward and redirect the mail to billyboy at domain.tld.
