I have email gateway 7.5 connected to Server With Hyper-V in a port.
When I try make telnet not always respond the Exchange Server, The answer is connect failed to port 25 of the mail server.
I check the settings of Email Gateway, but is correct.

In hyper-V a VM with Exchange Server.
One Virtual Switch with port connect to Email Gateway.
anyone has any idea because the port does not respond?
