To instruct the IP filter to always allow email messages from certain trusted addresses and domains, configure the approved senders list. Although email messages will be able to pass through the IP filter, InterScan™ Messaging Security Appliance (IMSA) might still take action on the email messages if they violate any of the rules that you configured for the policy.
To configure the approved senders list:
Choose IP Filtering > Approved List from the menu. The Approved List screen appears showing the following:
Domain—The approved domain.
IP Addresses—The approved IP address.
Timestamp—The time the domain or IP address was added to the list.
Status—The
current status of the allowed domain or IP address. A green check mark
means that IMSA is currently allowing email from the
domain or IP address to pass through the IP filter. A red X
means that IMSA saved the approved sender information but
the sender is not enabled.
To change the display, do any of the following:
If too many items appear on the list, click the arrow buttons on top of the list to move to the next page.
To change the number of items that appears in the list at one time, select a new display value from the drop down box on the bottom of the table.
To delete a sender, select the check box next to it and click Delete.
