My external email is routed through a 3rd party spam filtering service and I continually get the maximum connections per source has been exceeded error. I want to be able to increase the per source limit, but only for that single connection. I don't wnat to increase ti for all incoming connections. Can that be done? If so, how?

Likley create a separate receive connector just for this source ip and up the limit for this connector.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi slagtron01: I want to know that where does the error happen. If the error happened on 3^rd party spam filter, you can communicate with provider to know how to increase connection and per source limit. If the error happened on exchange server, I can offer you solution: 1.Open an Exchange Management Shell (Powershell with the Exchange snap-in) 2.Type get-receiveconnector. This lists all connectors of your Exchange environment 3.Type get-receiveconnector -id “unique receive connector name” | fl 4.Look for MaxInboundConnectionPerSource in the overview 5.To adjust the MaxInboundConnectionPerSource, type set-receiveconnector -id "unique receive connector name" -MaxInboundConnectionPerSource 50110000
