Chapter 23 Text Resources

Using Text Resources

To use message filter action variables in disclaimers, create a message disclaimer (via the Text Resource
page in the GUI or the

textconfig

command), and reference the variable:

The

add-footer()

action supports non-ASCII text by adding the footer as an inline, UTF-8 coded,

quoted printable attachment.

Disclaimer Stamping and Multiple Encodings

AsyncOS includes a setting used to modify the way disclaimer stamping with different character
encodings works. By default, AsyncOS attempts to place the disclaimers it attaches within the body part
of an email message. You can use a setting configured within the

localeconfig

command to configure

the behavior if the encodings of the body part and the disclaimer are different. To understand this setting,
it is helpful to view an email message as consisting of several parts:

The message body after the first blank line may contain many MIME parts. The second and following
parts are often called “attachments,” while the first is often called the “body” or “text.”

A disclaimer can be included in an email as either an attachment (above) or as part of the body

$threat_description

Replaced by a description of the Outbreak Filters threat.

$threat_level

Replaced by the message’s threat level (score 0 - 5).

$threat_verdict

Replaced by Yes or No, depending on the Message Modification
Threat Level threshold. If the viral or non-viral threat level of a
message is greater than or equal to the message modification
threat level threshold, the value of this variable is set to Yes.
