An additional aspect of this scenario is that when I have used ssh to connect to this mail server via the internal network, I am able to ssh out of the machine to one of the internal networks or remotely to a different network. If no one else has had this problem with 7.1 then it is obviously something I have done, but right now I am at a loss.
Assuming that the mail server’s routing table is correct, you will need some tcpdump to understand if the packets from outside reach the server (and then it discards them).
I would do this: 1. Ensure that the mail server still has a valid default gateway and a correct routing table 2. start tcpdump on the gateway 3. start tcpdump on the mail server 4 Try to connect to the mail server from outside.
