I have Exchange 2007 running in a Windows 2003 Domain. We use Postini as our spam solution. Now when Postini detects a spam message, it leaves the spam in a "Message Center" that must be accessed thru a web browser. We went to get those messages to go straight to the Junk E-Mail folder in Outlook 2003/2007.
We can have Postini modify the header so that the subject of the message would be something like "SPAM: <subject>." What we can't find is a way for Exchange to process any messages with the "SPAM" designation to push it to the Junk E-Mail folder. Obviously, it can be done by rules in Outlook, but that is a poor solution to a domain of 100 users. It would require manually changing the rules on each workstation.
Is there a way in Exchange to set a "global rule" for messages? Or if anyone has any better suggestions, that would be greatly appreciated.
