Enabling the Dynamic Always Permit List function allows some mail exchanged between a sender/recipient address pair to bypass antispam filtering. When mail between a sender to a
recipient does not trigger an antispam filter a specified number of times, that sender/recipient address pair is added to the Dynamic Always Permit List. Antispam analysis is not
performed on mail between this sender/recipient address pair. When a specified timeout period has elapsed, the address pair is removed from the list.
Steps
-
From the section Dynamic Always Permit List on the Always Permit tab, mark the check box Enable Dynamic Always Permit List.
Functionality is enabled by default.
-
In the field Occurrence, enter the number of spam-free email exchanges (from 1 to 5) required before a sender/recipient pair is added to the list.
The default is 1.
-
In the field Timeout, enter a value for the timeout interval in hours (from 1 to 720).
The default is 720.
-
(Optional) Clear the list manually; click the button Clear Dynamic Always Permit List.
If you disable this function, the list is automatically cleared.
