On the POP3 > Exceptions tab you can define client hosts/networks and sender addresses that shall be excluded from various security features.

To create an exception, proceed as follows:

  1. On the Exceptions tab, click New Exception List.

    The Add Exception List dialog box opens.

  2. Make the following settings:

    Name: Enter a descriptive name for this exception.

    Skip these checks: Select the security checks that should be skipped. For more information, see Email Protection > POP3 > Malware and Antispam.

    For these client hosts/networks: Add or select the source hosts/networks (i.e., the hosts or networks messages originate from) that should skip the security checks. How to add a definition is explained on the Definitions & Users > Network Definitions > Network Definitions page.

    Note – No exception needs to be created for localhost because local messages will not be scanned by default.

    When selecting this option, the Client hosts/networks dialog box opens. You can add a host or network by either clicking the plus symbol or the folder symbol.

    OR these sender addresses: Select the senders' email addresses that should skip the defined security checks.

    When selecting this option, the Senders box opens. You can either enter a complete valid email address (e.g., jdoe@example.com) or all email addresses of a specific domain using an asterisk as wildcard (e.g., *@example.com).

    Note – Use the Senders option with caution, as sender addresses can easily be forged.

    Comment (optional): Add a description or other information.

  3. Click Save.

    The new exception appears on the Exceptions list.

To either edit or delete an exception, click the corresponding buttons.
