Something's wrong in that case, MailScanner should never touch any 
Received: header, under the default shipped settings. That text should 
go in the X-MailScanner: header where it is legit.

Please try it with a default MailScanner.conf and see if it still does 
it. It shouldn't, and I don't believe it does on other people's systems.

That's about a year old, but I haven't made changes to that code in a 
very long time (that I can remember, anyway).
