Hello,
I have an Exchange 2013 machine that has both roles installed on it. When I try to connect via Telnet to port 25 I do not receive the SMTP banner that I would normally expect to receive. Instead I only receive a message to: 'Press any key to continue'.
I have checked the Receive connectors for the machine and the Default Frontend receive connector is enabled for all addresses and for IPv6 and IPv4. All services are running. We can Telnet to 25 from the server but not from other servers located on the same subnet.
My other three Exchange 2013 servers are working as expected.
Anyone have any thoughts on how I can troubleshoot this?
Thanks,
Matt
