Filter
Because automated email messages that are sent from the Cisco IronPort appliance (such as email alerts 
and scheduled reports) may contain URLs or other information that may cause them to be incorrectly 
identified as spam, you should do the following to ensure their delivery:
Include senders of these messages in an incoming mail policy that bypasses anti-spam scanning. See 
Headers Added During Anti-Spam Scanning 
If either anti-spam scanning engine is enabled for a mail policy, each message that passes through 
that policy will have the following headers added to the message: 
X-IronPort-Anti-Spam-Filtered: true 
X-IronPort-Anti-Spam: result 
The second header contains information that allows Cisco Support to identify the rules and engine 
version used to scan the message. Result information is encoded proprietary information and is not 
customer-decodable. 
Cisco Intelligent Multi-Scan also adds headers from the third-party anti-spam scanning engines.
You can define additional custom headers to be added to all messages for a given mail policy that 
are positively identified as spam, suspected to be spam, or identified as unwanted marketing mail.
