Using Exchange 2003...
We want to block/bounce e-mail from a specific address to all users with the exception of 5 specific users.
We are currently having all mail from this address forwarded to a mailbox which then runs certain rules in Outlook to either bounce the message or forward it to the "allowed" users. This is not the desired approach...it is not fully automated and suffers from a few other challenges.
I have found the "Delivery Restrictions" dialog in the "Exchange General" tab of user properties in AD. In there is the option for allowing mail "from everyone except"...I click the "add" button, but it appears to want an AD object to complete the task. I want to enter an outside e-mail address (email@example.com).
Am I barking up the wrong tree?
What is the best approach to accomplish this?
