Configure SMTP for outbound emails

Google Cloud Platform doesn’t allow SMTP traffic through default ports: 25, 465, 587. Check Google cloud documentation to learn how to use a VPN to bypass these restrictions or use a different port for sending emails from your application.

Follow these steps:

  • Log in to the Administration Control Panel of phpBB and navigate to the “Client communication -> E-mail settings” section.

  • Enter the settings for your SMTP server. For example, to use a Gmail account, use these settings. Replace USERNAME and PASSWORD with your Gmail account username and password respectively.

      Use SMTP server for e-mail: Yes
      SMTP server address: tls://
      SMTP server port: 587
      Authentication method for SMTP: PLAIN
      SMTP username:
      SMTP password: PASSWORD

To configure the application to use other third-party SMTP services for outgoing email, such as SendGrid or Mandrill, refer to the FAQ.

NOTE: If you are using Gmail as the outbound email server and have experienced issues trying to send emails correctly, check the Gmail SMTP troubleshooting page to learn the causes of these issues and how to solve them.
