We have a single Exchange 2003 SP1 server in one of our organization which is not exposed to internet and we forward all mails to one of the Smarthost. We would like to enable the Exchange server/SMTP Virtual server to accept the extended message properties which are sent anonymously, so that we could see some of the extended attributes like SCL ratings in our user's mail box. "Plz let me if this is recommended???" We do have Symantec Bright mail Anti Spam installed in our Exchange server, which will stamp the SCL property of the receiving messages. But we would like to see the SCL ratings using outlook...
