Chapter 8      Anti-Spam
Each anti-spam solution has a group of configuration settings associated with it. 
These settings apply only to the corresponding engine, and are available on the 
IronPort Anti-Spam page and IronPort Intelligent Multi-Scan page on the 
Security Services menu, and the Incoming/Outgoing Mail Policies Anti-Spam 
settings page. The scanning solution’s specific settings are discussed in the 
corresponding sections. The IronPort Anti-Spam and IronPort Intelligent 
Multi-Scan pages also display a list of their most recent anti-spam rule updates.
For more information on configuring global anti-spam settings, see:

For more information on configuring anti-spam scanning on a per recipient basis,

Anti-Spam Scanning and Messages Generated by the Cisco 
IronPort Appliance
Cisco recommends that recipients who receive email alerts, scheduled reports, 
and other automated messages from the Cisco IronPort appliance be placed in an 
incoming mail policy that bypasses anti-spam scanning. These messages may 
contain URLs or other information associated with spam sources not ordinarily 
found in a company's mail stream which may occasionally cause such messages 
to be marked as SPAM. Alternatively, you can choose to add the IP addresses 
sending mail on behalf of the Cisco IronPort appliance to the 'WHITELIST' policy 
in the host access table (see 
). For 
more information, please contact your authorized Cisco IronPort appliance 
support center.
IronPort Anti-Spam Filtering
IronPort Anti-Spam uses conventional techniques and innovative 
context-sensitive detection technology to eliminate a diverse range of known and 
emerging email threats.
