I was hoping to use the replace capabilities for two users. Me for testing and one other. This one user sends to a number of people who don't use outlook, and for some reason the email generated by Outlook for Mac 2011 periodically contains winmail.dat attachments for some reason. I don't want to do anything for 99% of the users emails, so hence the rule.

Don't rely on sending all your outbound mail via MailScanner and having it convert the TNEF into MIME for you - it's simply slower and error prone due to the lack of documentation of the TNEF format; it should be 'fixed' at the Exchange end.

I know, but since I only needed to do it for one user, I thought it would be easier to do it on the MailScanner side than affecting all users with the MIcrosoft settings.
