Hello,
We have a spam filtering appliance in front of Exchange that is Internet facing, thus all mail to Exchange server is coming from this appliance's IP address. I'm starting to see backlogged mail getting queued and users saying messages are coming in hours or days delayed. I've already changed the values on the Default Front End receive connector:
MaxInboundConnection 5000
MaxInboundConnectionPerSource 100
MaxInboundConnectionPercentagePerSource 100
This seems logical as all mail will be coming from the same source IP. However the problem is still occurring, am I missing another value to change? Interestingly I have not seen any Error in event viewer indicating that connections have been exceeded.
Any assistance is appreciated!
