forwarded emails

[Walt Thiessen]

How does MailScanner handle forwarded emails?

For instance, let's say that joe at domain.tld sends an email to 
bill at domain.tld. Bill has bill at domain.tld set up to forward to 
billyboy at domain.tld.

If there is a whitelist rule that whitelists emails from joe at domain.tld 
to billyboy at domain.tld, will this particular forwarded email get 
delivered due to that whitelist rule?
