I have a client that is using a mindspring mail account that requires them to use port 587 for their smtp service. They have ip inspects running on their router. The client makes the initial connection, then nothing happens. I am wondering if its the ip inspect configuration that is causing the issues, any thoughts? Here is the setup for the port in question:
