First we suspected an issue between the Mailscanner
server and the 
Exchange servers. But after many tests all seem to be
OK on this point.

When we disable SpamAssasin from the mailscanner.conf,
the queues 
decrease quickly, but after hours the queues increase
When we disable the Anti-virus from mailscanner.conf,
we have no improvement.
When we diable Mailscanner, and use only postfix, we
have no problem.

Volume : 150 000 messages per day
