You don't want to play with header checks. The above is correct for
MailScanner not to scan your mail (As Postfix won't direct the first 2
IP addresses to the hold queue for scanning, first rule matches). The
easiest way to do this is in MailScanner. Just go to Remove These
Headers = and point it to a ruleset. In the ruleset have something like:

From:   192.168.10.50   Received:
From:   192.168.10.1     Received:
FromOrTo:   Default

Obviously add any other headers you want removed and restart MailScanner.
