  • 421 4.3.2 Service Not Availabe

    Good day,

    I have successfully (sort of) setup my Exchange 2010, now i am having difficulties to telnet to port 25. I have checked both Default Receive connectors are unchanged, Windows Firewall disabled. Antivirus firewall disabled. If there are any ideas, please help, I am telneting from within this server and on a client machine and still get the same error message. Thank you.

    You may need to post the default Recieve connector settings via
    get-receiveconnector |fl
    If you have set it to listen to 127.0.0.1,check if you can telnet localhost,Check if annonymous connections are allowed.
