Global

On the Email Protection > POP3 > Global tab you can configure basic settings for the POP3 proxy.

To configure the POP3 proxy, proceed as follows:

  1. Enable the POP3 proxy.

    Click the toggle switch.

    The toggle switch turns amber and the POP3 Settings area becomes editable.

  2. Select the allowed networks.

    Add or select the networks that should be allowed to proxy POP3 traffic. Typically, this is the internal network. How to add a definition is explained on the Definitions & Users > Network Definitions > Network Definitions page.

    Caution – It is extremely important not to select an Any network object, because this introduces a serious security risk and opens your appliance up to abuse from the Internet.

  3. Click Apply.

    Your settings will be saved.

    The toggle switch turns green.

To cancel the configuration, click the amber colored toggle switch.

Live Log

The POP3 Live Log logs the POP3 proxy activities, showing all incoming emails. Click the button to open the live log in a new window.

Note – In the log, you can see the public source IP address (scrip) from all incoming emails. If an incoming mail was sent from a private IP address range, that IP address cannot be displayed and the log shows srcip=0.0.0.0. Typical private IP address ranges are for example 127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12 or 192.168.0.0/16.
