mailscanner

I have installed Postfix with MailScanner on CentOS 5.4 as a smarthost for Exchange 2007. When a message gets quarantined and I later release it (http://wiki.mailscanner.info/doku.php?id=documentation%3Aconfiguration%3Amta%3Apostfix%3Ahow%5Fto%3Arelease%5Fquarantined%5Fmail), it gets delivered to the Exhcange box but does not appear in a user's mailbox.

Exchange message tracking log shows the message is marked as DUPLICATEDELIVER and therefore dropped.

How can I work around this situation? Maybe changing a message ID somehow while at the Postfix box or some other way?

Thanks.
