Gmail smtp server port 25

A classic!

By default, Gmail's SMTP server uses port 587, not port 25. Port 25 is typically used for sending emails using the Simple Mail Transfer Protocol (SMTP) for sending emails between mail servers, whereas port 587 is used for sending emails from a mail client (like a desktop email program or a mobile app) to a mail server.

  1. Check your email client or script settings to ensure they match the default settings above.

  3. Verify that your Gmail account is set up correctly and that you're using the correct username and password.
  4. If you're still having issues, try using a different email client or script, or contact your ISP or email provider for assistance.
