Configure Email Settings

On the System Settings > Configuration page, you can enable the WebBlocker Server to send outgoing email notifications. When enabled, specify the IP address of the email server, the port and encryption settings, and specify user credentials to send to the email server (if necessary).

When you select the encryption setting, the option you select specifies whether TLS encryption is used, and the type of TLS encryption. The available encryption settings include:

  • None — TLS encryption is not used
  • Allowed — Uses TLS encryption, if available (default)
  • Required — Requires TLS encryption for SMTP connections
  • Required with verification — Messages are only sent over TLS encrypted sessions if the remote SMTP server certificate is valid and if the server certificate name matches a known pattern. If the certificate fails verification, the message is deferred.

  2. In the Email Settings section, select the Enable outgoing email check box.
  3. In the Email Server IP Address text box, type the IP address or FQDN of the email server to use to send email.
