Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server administrator or Internet service provider (ISP) for additional assistance.


    구글에서는 아래와 같이 해보라는데, 안된다..ㅋㅋ
    Telnet을 해봐도 응답도 없고..ㅡㅡ;;

    Check that you are using the correct outgoing mail server port and encryption: port 587 with TLS. You can also try using port 25 and/or SSL encryption. If the problem persists, try running a telnet test to determine whether the port is blocked on your network.

    To better diagnose the problem, you'll need to run a telnet test, which will check that your computer can contact our POP servers.

    If you're running Windows Vista, you'll first need to enable the Telnet feature:

    1. Click the Start button, then Control Panel, and Programs.
    2. Click Turn Windows Features On or Off.
    3. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
    4. In the Windows Features box, check the box labeled Telnet Client, and click OK. (It may take a few minutes for the installation to complete.)

    To run the telnet test on a Windows computer:

    1. Open the Start menu, and select Run.
    2. Enter command in the Open: field, and click OK.
    3. Enter 'telnet pop.gmail.com 995,' and hit Enter.

    If the telnet test produces an error, it indicates that your network is blocking access to Gmail's POP servers. Please contact your local network administrator or your Internet Service Provider's customer support department for further instructions.

    그래서 결론은 포트를 변경했다.

    Still can't send mail?

    If you tried configuring your SMTP server on port 465 (with SSL) and port 587 (with TLS), but are still having trouble sending mail, try configuring your SMTP to use port 25 (with SSL). 



     smtp port: 465 (with SSL)
    이것을 사용하니, 작동한다..ㅠㅠ

    이 문제로 얼마나 삽질했던가..ㅠㅠ
