Random internal email is going to "some" users junk in outlook. There are too many to make safe sender locally. This just started. I have Exchange 2010 with an Edge and CAS. Is there somewhere within the Hub that I can make intra domain mail safe? MS Anti-spam is set up on the edge and allowed on the IP allowed is the Hub and Mailbox database servers IP addresses. I would have thought that setting it up this way would ALWAYS allow internal email to be delivered to users inboxes.
