Content Filters
You can create content filters to be applied to messages on a per-recipient or 
per-sender basis. Content filters are similar to message filters, except that they are 
applied later in the email pipeline — after a message has been “splintered” into a 
number of separate messages for each matching Email Security Manager policy. 
The functionality of content filters is applied after message filters processing and 
anti-spam and anti-virus scanning have been performed on a message.
For more information about Content Filters, see 
Virus Outbreak Filters
IronPort’s Virus Outbreak Filters feature includes special filters that act 
proactively to provide a critical first layer of defense against new outbreaks. 
Based on Outbreak Rules published by IronPort, messages with attachments of 
specific filetypes can be sent to a quarantine named Outbreak.
Messages in the Outbreak quarantine are processed like any other message in a 
quarantine. For more information about quarantines and the Work Queue, see 
See
