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:
On the Exceptions tab, click New Exception List.
The Add Exception List dialog box opens.
Make the following settings:
Name: Enter a descriptive name for this exception.
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., firstname.lastname@example.org) 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.
The new exception appears on the Exceptions list.
To either edit or delete an exception, click the corresponding buttons.
