About precedence
Determining the precedence of different types of filtering for a particular message
rests on many factors.
If more than one verdict matches a message, the following applies:
■
Any matching verdict that calls for an action of defer or reject takes precedence
over verdicts that call for other actions.
■
If multiple matching verdicts call for defer or reject, the one of those verdicts
that appears first in the precedence list (see below) takes precedence.
■
If no matching verdict calls for an action of defer or reject, then the matching
verdict that appears first in the precedence list takes precedence.
■
Although a verdict can call for multiple actions, only one verdict determines
the actions that are taken on a message. Actions called for by lower precedence
verdicts are not applied.
Order of precedence:
■
Virus attack
■
Worm
■
Virus
■
Spyware or adware
■
Suspicious attachment (suspected virus)

Unscannable
