level specified for the rule that is applied. If the final SPAM score exceeds the
threshold level, then the message is considered SPAM and the specified action is
taken. Otherwise, the message is allowed to pass and BitDefender adds scan
information to the e-mail header.
6.1.2. Content Filtering
If the message is not deleted during antispam filtering, it is then verified according to
a specific content filtering group policy.
The message is checked against the content filtering rules, by order of priority, until
the sender and the recipients of the message match a rule. The message is then
processed according to the options specified by that rule.
● If the filtering option set for the rule is Do not scan, the message is not processed
using content filtering.
● If the filtering option set for the rule is Scan, the message is checked according to
the content filtering options specified by the rule. If the message matches the rule,
the content filtering stops and the specified actions are taken on the message.
Otherwise, the message is allowed to pass without any action taken.
