Evaluation Key
Your Cisco appliance ships with a 30-day evaluation key for the Cisco Anti-Spam software. This key is 
not enabled until you accept the license agreement in the system setup wizard or Security Services > 
IronPort Anti-Spam pages (in the GUI) or the 
systemsetup
 or 
antispamconfig
 commands (in the CLI). 
Once you have accepted the agreement, Cisco Anti-Spam will be enabled, by default, for the default 
incoming Mail Policy. An alert is also sent to the administrator address you configured (see the System 
Setup Wizard, 
) noting that the Cisco Anti-Spam license will expire in 30 days. 
Alerts are sent 30, 15, 5, and 0 days prior to expiration. For information on enabling the feature beyond 
the 30-day evaluation period, contact your Cisco sales representative. You can see how much time 
remains on the evaluation via the System Administration > Feature Keys page or by issuing the 
featurekey
 command. (For more information, see 
.)
Step 6
(Recommended) Enable SenderBase Reputation Service 
scoring for each inbound mail flow policy, even if you 
are not rejecting connections based on SenderBase 
Reputation Scores. 
For each inbound mail flow policy, ensure that “Use 
SenderBase for Flow Control” is On.

Step 7
If your Email Security appliance does not connect 
directly to external senders to receive incoming mail, but 
instead receives messages relayed through a mail 
exchange, mail transfer agent, or other machine on your 
network, ensure that relayed incoming messages include 
the original sender IP address. 
Step 8
Prevent alert and other messages generated by your 
appliance from being incorrectly identified as spam. 
Step 9
(Optional) Enable URL filtering to strengthen protection 
against malicious URLs in messages. 
Step 10
Test your configuration. 
 
Step 11
(Optional) Configure settings for service updates 
(including anti-spam rules.) 
Scanning rules for both anti-spam solutions are retrieved 
by default from the Cisco update servers.
