Hi all,
just finished installing exchange 2013 and all went well. Internally, everything works perfectly. However, I then moved my testing externally. Browsing to https://mydomain/owa times out - as does https://mydomain/ecp Also, I cannot telnet to my mail server either: telnet mydomain 25 times out. I can though telnet mydomain 143 and telnet mydomain 110 no problem.
I have setup the receive connector as per the instructions (in fact, it was already setup) the frontend default allows anonymous access (as it should). Windows firewall is off. Router forwarding ports fine.
I can telnet 25 locally and as I said, everything works internally. Clearly, there is another step that has to be taken to allow external access to the port 25 and also for owa and ecp. I have double checked the SERVERS - VIRTUAL DIRECTORIES area and all the external url are correct. Can someone help please?
