We have an issue where our firewall is blocking a message being sent from one of our Exchange Hub servers to a blacklisted IP address, from the inside IP of our exchange server on port 57638 to the outside IP port 25.  My concern is that the internal Hub server should not be sending any e-mail to an outside IP, since it should be routed through the Edge server and then sent from there.  How can I investigate this on the Exchange/Server side and see why this is happening?
