  How Content Filters Work
Add/Edit Header
Inserts a new header into the message or modifies an existing header.
Header name. Name of new or existing header.
Specify value of new header. Inserts a value for the new header into the 
message before delivering.
Prepend to the Value of Existing Header. Prepends the value to the existing 
header before delivering.
Append to the Value of Existing Header. Appends the value to the existing 
header before delivering.
Search & Replace from the Value of Existing Header. Enter a search term 
to find the value you want to replace in the existing header in the Search for 
field. Enter the value you want to insert into the header in the Replace with 
field. You can use a regular expression to search for the value. Leave the 
Replace with field empty if you want to delete the value from the header.
Add Message Tag
Inserts a custom term into the message to use with RSA Email DLP policy 
filtering. You can configure a RSA Email DLP policy to limit scanning to 
messages with the message tag. The message tag is not visible to recipients. 
For information on using messages tags in a DLP policy, see 
.
Add Log Entry
Inserts customized text into the IronPort Text Mail logs at the 
INFO
 level. The 
text can include action variables. The log entry also appears in message 
tracking.
Encrypt and Deliver Now 
(Final Action)
Encrypts and delivers the message, skipping any further processing.
Encryption rule: Always encrypts the message or only encrypts it if an 
attempt to send it over a TLS connection first fails. See 
Encryption Profile. Encrypts the message using the specified encryption 
profile, then delivers the message. This action is for use with a Cisco 
Encryption Appliance or a hosted key service.
Subject. Subject for the encrypted message. By default, the value is 
$Subject
.
Bounce (Final Action)
Sends the message back to the sender.
Skip Remaining Content 
Filters (Final Action)
Delivers the message to the next stage of processing, skipping any further 
content filters. Depending on configuration, this may mean deliver the 
message to recipient(s), quarantine, or begin Outbreak Filters scanning.
Drop (Final Action)
Drops and discards the message.
