Руководство Пользователя для Cisco Cisco Content Security Management Appliance M160

AsyncOS counts incoming mail dependent on the number of recipients per message. For example, an 
incoming message from example.com sent to three recipients is counted as three messages coming from 
that sender.

Because the messages blocked by reputation filtering do not actually enter the work queue, the appliance 
does not have access to the list of recipients for an incoming message. In this case, a multiplier is used 
to estimate the number of recipients. This multiplier is based on research of a large sampling of existing 
customer data.

As messages proceed through the email pipeline, they can apply to multiple categories. For example, a 
message can be marked as spam or virus positive; it can also match a content filter. 

The various verdicts follow these rules of precedence:

Outbreak Filters quarantining 



(in this case the message is not counted until it is released from the quarantine and again 
processed through the work queue)

Spam positive

Virus positive

“clean.”
