I have a requirement to send a notification to an external email address whenever a message that meets certain criteria appears in a users mailbox. This is similar to sending an auto-reply, but always sending a specific message (not forwarding the original message) to the external email address, not the sender.
I can't quite figure out how to do this in Exchange 2003/Outlook 2003. It has to be a server side rule that does not require the Exchange mailbox user is logged in.
