Clean Messages Accepted: Mail that is accepted and that 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.

If messages match a message filter and are not dropped or bounced by the filter,
they are treated as clean. Messages dropped or bounced by a message filter are not

How Messages Are Categorized
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:
Virus 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),
followed by spam positive, virus positive, and matching a content filter.

Virus 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),
followed by spam positive, virus positive, and matching a content filter.
For example, if a message is marked as spam positive, and your anti-spam settings
are set to drop spam positive messages, the message is dropped and the spam
counter is incremented. Further, if your anti-spam settings are set to let the spam
positive message continue on in the pipeline, and a subsequent content filter
drops, bounces, or quarantines the message, the spam count is still incremented.
The content filter count is only incremented if the message is not spam or virus
positive.
