Because 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 and based upon research
of a large sampling of existing customer data.

Clean Messages: Mail that is accepted and is deemed to be virus and spam free — the most accurate
representation of clean messages accepted when taking per-recipient scanning actions (such as
splintered messages being processed by separate mail policies) into account. However, because
messages that are marked as spam or virus positive and still delivered are not counted, the actual number
of messages delivered may differ from the clean message count.
