It's pleasing to hear and if you are happy to take the risk, that's good.

Indeed. The problem is that MailScanner is checking the incoming directory
(That is the one it is collecting from) and setting the out going one (The
one it puts mail into when it's been cleaned etc) to be the same. So you
can just remove hashing from the deferred queue and leave the defer as
hashed if it's easier or what ever mix suits as long as both sides are the
same (In this instance your problem came up because the Postfix defaults
happen to be different from the eyes of MS)

Yeah, fair point well made :-)
