Content Control 52
Editing a Content Control definition

• Copy the message to another address Selecting this action will make a copy of the mes-
sage and send the copy to the address you specify in the "parameter" field. The original
message will not otherwise be diverted or altered in transit and will be delivered nor-
mally.

• Forward the message then delete it This action will divert the message to the address
you specify in the "parameter" field. When you select Forward and delete, this action
will cause all content control processing to terminate for the message, because it will be
effectively removed from circulation.

• Move the message to a directory as a file This action diverts the message to a "quaran-
tine directory". When you click the Set button, Mercury will prompt you to select a
directory, which can be anywhere on the local machine or on your network. Mercury will
move the message into this directory as a file and remove it from the queue so that no
further processing or delivery occurs.

• Delete the message Just like it says - this action deletes the message, end of story. All
content control processing ceases at this point, and the message is gone forever. We sug-
gest you use this action with considerable care.

Header addition and advanced options
As well as taking the action you specify on the message, Mercury can add certain headers to
mail to indicate the results of Content Control processing.

Add graphical X-UC-Weight headers for unacceptable mail When this control is checked,
Mercury will add a header called X-UC-Weight ("UC" stands for unacceptable content) to
any message that has a weight greater than the activation weight for the set (see the Message
tests page for more information on how the activation weight is calculated). The X-UC-
Weight is “graphical”, in that it contains a little graph that indicates how unacceptable the
message actually was. The graph consists of one to four hash characters, with the following
meaning:

[####] The message has been Blacklisted, or has a weight greater
than 9990
[### ] The message's weight is more than three times greater than
the activation weight for the set (in other words, it's probably
particularly odious)
[## ] The message's weight is more than twice but less than three
times the activation weight for the set
[# ] The message's weight is more than the activation weight for
the set, but less than twice the activation weight

After the graphic, the actual weight of the message is shown in brackets.

Add graphical X-AC-Weight headers for acceptable mail It is possible to assign negative
weights to a message during content control processing - in fact, this is what the whitelist
does (it assigns a weight of -9999). If a message comes through the content control process
with a negative weight, it is regarded as Acceptable - something important or desirable. If you
have rules in place that have negative weights to promote the value of a message, you can
instruct Mercury to add a header called X-AC-Weight ("AC" stands for acceptable content)
to any messages that end up with a negative weight. This can be a very handy way of high-
lighting messages with important content - you can use filtering rules later in the process to
