SMTP Server

Required user role when using Tenable Nessus Manager: System Administrator

The SMTP Server page allows you to configure a Simple Mail Transfer Protocol (SMTP) server. Once you configure an SMTP server, Nessus can email HTML scan results to the list of recipients that you specify in the scan settings.

Note: The SMTP Server page is not available when Tenable Nessus is linked to Tenable Vulnerability Management.

    The About page appears.

  2. In the left navigation bar, click SMTP Server.

    The SMTP Server page appears.

  3. Configure the settings as necessary.
