Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

The first prompt determines whether or not a message header’s encoding should be changed to match 
that of the message body if the header is changed (via a filter, for example).

The second prompt controls whether or not the appliance should impose the encoding of the message 
body on the header if the header is not properly tagged with a character set.

The third prompt is used to configure how disclaimer stamping (and multiple encodings) in the message 
body works. Please see “Disclaimer Stamping and Multiple Encodings” in the “Text Resources” chapter 
in the Cisco IronPort AsyncOS for Email Configuration Guide for more information.

In the following example, the 

filter

 command is used to create three new filters:

The first filter is named 

. It uses the 

body-size

 rule to drop messages larger than 10 

megabytes. 

The second filter is named 

. It uses the 

attachment-filename

 rule to drop messages that 

contain attachments with the filename extension of 

.mp3

. 

Footers or headings are added in-line with the message body whenever 

possible. However, if the footer or heading is encoded differently 

than the message body,and if imposing a single encoding will cause 

loss of characters, it will be added as an attachment. The system will 

always try to use the message body's encoding for the footer or 

heading. If that fails, and if the message body's encoding is US-

ASCII, the system can try to edit the message body to use the footer's 

or heading's encoding. Should the system try to impose the footer's 

or headings's encoding on the message body? [N]> y

Behavior when modifying headers: Use encoding of message body

Behavior for untagged non-ASCII headers: Impose encoding of message 

body. Behavior for mismatched footer or heading encoding: Try both 

body and footer or heading encodings
