We had misconfigured receive connector in exchange 2007, which caused it to be an open relay for a couple of days. I've since disabled that receive connector, only leaving the default. When I run a open relay tester online, it says its closed. However, i'm still seeing relayed messages in the outbound queue that are sticking.
Does anyone know what else I should be checking to make sure i'm secure or perhaps how I relayed messages are still making it in? Please don't hesitate to ask clarification or current settings. Thanks!
