Wondering if someone could point me in the right direction. I just finished upgrading from 5.0.18 to 7.2.1 but I also changed the way we connect to the server. The server use to just have a single outside IP address. Now it is a single inside IP address and I nat the outside IP address to the inside. I can connect on all ports outside of the network except port 25 which I can connect to on the inside network.
In the deferred queue the error is "delivery temporarily suspended: Connect to firstname.lastname@example.org[Public IP]:7025: connections timedout".
I have a feeling that the Public IP should be my internal IP now that it has changed. But where would I change this?
Any help is appreciated.
