Looking for a way to stop emails that are securely relayed anonymously off your internal receive connector from being caught by outlook 2010 junk filter?
The MS Exchange Team sheds some light on the issue here.
So a little history on my issue. I currently have a receive connector configured to allow anonymous email to be relayed with in our organization, to allow servers and such to send out notifications. we have had speratic issue with emails from our onbase servers being caught by outlook 2010's junk mail filters.
My first attempt to correct this issue as to add our domain to Outlooks safe sender list, but that had no effect as exchange would remove the entry after applying it. next I added the ms-exch-bypass-anti-spam permission to the anonymous user on for my receive connector and for awhile that worked. Recently though, we have started to have the issue resurface. After reading this post by the Exchange team I have learned that ms-exch-bypass-anti-spam only bypasses exchanges spam filters not Outlooks. At the recomendation of Microsoft I will be installing the anti-spam filters on our hub transport servers and add the IP's of our internal server to the safe list to have the actual spam score set to -1 to prevent the message from going into Outlooks junk filter.
-Till Next Time
