Hello, The PMG is trying to send out lots of Bounce reports to bogus destination we are receiving SPAM emails from. This is putting our IP address into Backscatter IP Blacklist and causing some issue when users are trying to send out emails. Some destination servers rejecting emails coming out from the PMG. One way to stop this is by disabling Bounce reports. I really dont want to do that since that will also apply to legit emails trying to come to us. Even if i wanted to do that where is that option in PMG? Whats backscatter score should be for this and how to better protect PMG from this sort of things?
