I configured various Whitelists, Blacklists and SCL Rules. What happens if an email causes multiple matches?
With Whitelisting, Blacklisting and SCL Rules it is possible for a single email to give rise to multiple matches. IMF Tune follows a “play safe” rule. When multiple conditions match, the lowest SCL rating is applied. For example if an email contains a keyword located in a blacklist and a keyword located in a whitelist than the email is whitelisted. Extending this concept further, if an email matches an SCL Rule configured to set the SCL to 5 and also matches a keyword located in a blacklist, than the final SCL will be 5. SCL Rules applying ‘increment by ‘and ‘decrement by’ operations are considered to have the lowest priority. The increments and decrements are only computed if no other match is found that would set the email to a fixed SCL value. If computed, increments and decrements add up so that the final SCL value is the net result.
