MailScanner will only think something is what you tell it via a  
ruleset. To use Mailwatch, you will need to whitelist the loopback  
interface ( assuming you have a fairly standard set up in  
the Mailwatch config file. MailScanner with therefore scan all mail  
received on any other interface including your address.  
What Postfix calls this (Via the hosts file or PTR record) is  
irrelevant to MS.
