12.1.1. Configuring Global Antispam Filters
Several global antispam filters can be configured to filter all of the incoming mail traffic,
in order to reduce the traffic on the server. These filters are used before a specific
group filtering policy is applied.
Note
We recommend you to configure these filters when BitDefender Security for Exchange
is installed on a gateway.
Click Global Filters to open the configuration window and follow these steps to
configure the global antispam filters:
Step 1/4 - Configure Allow / Deny IP List
Click the Allow / Deny IP List tab to configure the Allow / Deny IP List.
Allow / Deny IP List
The Allow / Deny IP List enables the administrator to specify IP addresses which are
denied access to the server. All incoming connections from addresses that appear on
the Deny IP List are dropped, provided that such addresses do not appear on the
Allow IP List.
