How Incoming Mail Messages are Counted
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.
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 was determined by Cisco IronPort Systems and is
based on research of a large sampling of existing customer data.

How Email Messages Are Categorized by the Appliances
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.
