Advanced

In case your Sophos UTM on AWS cannot send emails directly, you can configure a smarthost to send the emails. Proceed as follows:

1. Enable External SMTP server status on the Management > Notifications > Advanced tab.

   Click the toggle switch.

   The toggle switch turns amber and the External SMTP Server area becomes editable.

2. Enter your smarthost.

   You can use drag-and-drop. The port is preset to the default SMTP port 25.

   • Use TLS: Select this checkbox if you want to enforce STARTTLS when sending notifications. Note that notifications will not be sent if the smarthost does not support TLS.

3. Specify the authentication settings.

   If the smarthost requires authentication, check the Authentication checkbox and enter the corresponding username and password.

4. Click Apply.

   Your settings will be saved.

   The switch turns green.
