Cisco Cisco Email Security Appliance C190 Guia Do Utilizador

Enable for all messages. This option allows AsyncOS to rewrite URLs in all 
messages that meet or exceed the message modification threshold, including 
signed ones. If AsyncOS modifies a signed message, the signature becomes 
invalid.

Disable. This option disables URL rewriting for Outbreak Filters.

You can modify a policy to exclude URLs to certain domains from modification. 
To bypass domains, enter the IPv4 address, IPv6 address, CIDR range, hostname, 
partial hostname or domain in the Bypass Domain Scanning field. Separate 
multiple entries using commas.

The Email Security appliance can append a disclaimer message above the heading 
of a suspicious message to warn the user of its content. This disclaimer can be in 
HTML or plain text, depending on the type of message.

Select the disclaimer text you want to use from the Threat Disclaimer list or click 
the Mail Policies > Text Resources link to create a new disclaimer using the 
Disclaimer Template. The Disclaimer Template includes variables for outbreak 
threat information. You can see a preview of the threat disclaimer by clicking 
Preview Disclaimer. For custom disclaimer messages, you can use variables to 
display the threat level, the type of threat, and a description of the threat in the 
message. For information on creating a disclaimer message, see 

Messages quarantined by the Outbreak Filters feature are sent to the Outbreak 
quarantine. This quarantine functions like any other quarantine (for more 
information about working with quarantines, see the “Quarantines” chapter in the 
Cisco IronPort AsyncOS for Email Daily Management Guide) except that it has a 
“summary” view, useful for deleting or releasing all messages from the 
quarantine, based on the rule used to place the message in the quarantine (for 
Outbreak Rules, the Outbreak ID is shown, and for Adaptive Rules, a generic term 
is shown). For more information about the summary view, see
