Cisco Cisco Email Security Appliance C390 사용자 가이드

Use the IronPort SenderBase Reputation service to drill down on and examine 
the relationship between specific IP addresses, domains, and organizations to 
obtain more information about a sender. 

Drill down on specific senders to obtain more information about a sender 
from the IronPort SenderBase Reputation Service, including a sender’s 
SenderBase Reputation Score and which sender group the domain matched 
most recently. Add senders to sender groups.

Drill down on a specific sender who sent a high volume of spam or virus 
email, as determined by the anti-spam or anti-virus security services.

Once you have gathered information on a domain, you can add the IP address, 
domain, or organization to an existing sender group (if necessary) by clicking 
“Add to Sender Group” from a domain, IP address, or network owner profile 
page. See the “Configuring the Gateway to Receive Email” chapter in the 
Cisco IronPort AsyncOS for Email Configuration Guide.

The Incoming Mail page provides access to real-time activity of all public 
listeners configured on your system and is comprised of two main sections: the 
mail trend graphs summarizing the top domains received (by total threat messages 
and by total clean messages) and the Incoming Mail Details listing.
