The blocked list shows the senders that InterScan™ Messaging Security Appliance (IMSA) blocked according to your IP profile settings. You can also instruct IMSA to always block email messages from certain untrusted addresses and domains. When IMSA receives an email message from a blocked sender, it rejects the message immediately. IMSA will not analyze this email message using the rules you created.
To configure the blocked senders list:
Choose IP Filtering > Blocked List from the menu. The Blocked List screen appears showing the following:
Domain—The blocked domain.
IP Addresses—The blocked IP address.
Type—The type of threat IMSA received from the sender.
Action—The action you instructed IMSA to take on email containing a threat.
Timestamp—The time the domain or IP address was added to the list.
Status—The
current status of the blocked domain or IP address. A green check mark
means that IMSA is currently blocking email from the
domain or IP address. A red X
means that IMSA saved the
blocked sender information but is not blocking sender's traffic.
To change the display, do any of the following:
To display items by threat type, select the type from the drop down box next to Filtered by.
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 move any blocked sender to the approved senders list, select the check box next to the sender, then click Send to Approved List.
To delete a sender, select the check box next to it and click Delete.
