Configure SMTP for outbound emails

In order to configure outbound email, follow the steps below:

  • Log in to the SonarQube dashboard and click on the “Administration” tab.

  • Browse to the “Configuration -> General settings -> General” menu.

  • Under the “Email” section, fill out the required information. The settings below configure SonarQube to send emails through a Gmail account. Replace USERNAME and PASSWORD with your Gmail account username and password, respectively.

      SMTP port: 587
      SMTP host:
      Secure connection: starttls
      SMTP password: PASSWORD
      SMTP username:
  • Save the changes.

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.
