I have an Exchange 2007 edge server that is the 2nd mail server in a mail server chain. It has to accept the hand off from another mail server on the perimiter.
Perimiter Email Server ---> Edge Server ---> Hub Server
My problem is that the IP Block List always adds the IP of the perimiter mail server to its rules. I've had to disable that option, but I'd like to use it. My questions are:
1. Can I add the perimiter email servers IP to the allowed IP list and still gain Anti spam functionality?
2. What can I do to correct this?
3. What suggestions do you have to increase the anti-spam functionality of our exchange setup?
