Configure SMTP for outbound emails

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, refer to the FAQ.

NOTE: If you are using Gmail as the outbound email server, your application’s attempts to send outgoing emails may be blocked by Gmail if it considers the authentication attempts to be suspicious. When this happens, you will receive a Gmail security alert at the corresponding Gmail address. To proceed, you will need to manually confirm the validity of the authentication attempt before Gmail will permit the application to send outbound emails. For more information on this and other Gmail issues related to outbound email from your application, refer to our Gmail SMTP troubleshooting page.
