Cisco Cisco Email Security Appliance C160 Betriebsanweisung

Domains which have connected to the appliance and could not be verified with a double-DNS lookup 
are automatically grouped into the special domain “No Domain Information.” You can control how these 
types of unverified hosts are managed via Sender Verification. See 

You can select the number of senders to show in the listing via the Items Displayed menu.

For senders listed in the Email Security Monitor table, click the sender (or “No Domain Information” 
link) to drill down for more information on the particular sender. The results are displayed on a Sender 
Profile page which includes real-time information from the SenderBase Reputation Service. From the 
Sender Profile page, you can drill down for more information on specific IP addresses or network owners 
(see 

).

You can also view another report, the Sender Groups report, by clicking the Sender Groups report link 
at the bottom of the Incoming Mail page. For more information about Sender Groups reports, see 

If you clicked a sender in the Incoming Mail Details table on an Incoming Mail page, the resulting 
Sender Profile page is listed with data for the particular IP address, domain, or organization (network 
owner). Sender Profile pages show detailed information for the sender. You can access a Sender Profile 
page for any network owner, domain, or IP address by clicking on the specified item in the Incoming 
Mail or other Sender Profile pages. Network owners are entities that contain domains; domains are 
entities that contain IP addresses. For more information on this relationship and how it relates to the 
SenderBase Reputation Service, see 

. 

The Sender Profile pages displayed for IP addresses, network owners, and domains vary slightly. For 
each, the page contains a graph and summary table for incoming mail from this sender. Below the graph 
is a table listing domains or IP addresses associated with the sender (the Sender Profile page for 
individual IP addresses does not contain the detailed listing) and an information section with the current 
SenderBase, sender group, and network information for the sender.

Network Owner profile pages contain information for the network owner, as well as the domains and 
IP addresses associated with that network owner. 

Domain profile pages contain information for the domains and IP addresses associated with that 
domain. 

IP address profile pages contain information about the IP address only. 

Each sender profile page contains the following data in the Current Information table at the bottom of 
the page:

The Global information from the SenderBase Reputation Service, including: 

IP Address, Domain Name, and/or Network Owner 

Network Owner Category (Network Owner Only)
