Configure external SMTP server

Learn how to configure external SMTP server to send email notifications.

Ensure that your SMTP server relay feature is turned on. Otherwise, any emails sent with a mail.from address in the notification that is different from your SMTP server default will fail.
If you use the Gmail SMTP server, you might need to generate an application-specific password for your account. Otherwise, you will get an error against the invalid password.

Navigate to Events notifications entry in the left navigation menu.

Click the Settings tab.

In the Email Settings section, click the External SMTP tab and then click Edit.

Configure the required fields.
