Do you have issues in connecting to Gmail SMTP Server? First make sure SSL is active for SMTP in your mail client. Next check that strong>allow authentication‘ is active for the SMTP server in your mail client. If SSL and allow authentication are active for the SMTP server, test Gmail SMTP Server connection by doing a Telnet test.

How to test Gmail SMTP Server connection?

If sending mails through Gmail SMTP Server does not work properly, test the connection by running a telnet test as described below.

If you are running Windows Vista, first enable Telnet feature before you run the Telnet test. To enable Telnet feature in windows Vista,

  • Click the Start button –> Control Panel –> Programs.
  • Click Turn Windows Features On or Off.
  • If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  • 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.)

Next run the telnet test to connect to Gmail SMTP Server.

Telnet Test on Windows (XP, Vista):

  • Go to Start –> Run
  • Enter “telnet smtp.gmail.com 465″ against Open: and click “OK”. If you are using Outlook 2007, enter “telnet smtp.gmail.com 587″ and click “OK”.

  • Open Utilities, and select Terminal.
  • Depending on what port you’re using to send, type ‘telnet smtp.gmail.com 25′ or ‘telnet smtp.gmail.com 587′ in the prompt window and press Enter.

When doing the Telnet test on windows or Mac, if the prompt window clears without throwing any errors, the Telnet test has passed.If you receive an error message, then access to Gmail SMTP Server has been blocked by your local network administrator or Internet Service Provider.
