Digest generation and Quarantines
Email Security will process your Message Rules in priority order. These rules are used, among other things, to determine a Spam Score for each message. The default set of rules contain a Confirmed Spam rule and Possible Spam rule. These two rules work together to determine whether a message is quarantined and whether a message is digested.

By default, a message with a Spam Score of between 100
and 140
will be quarantined but will be digested and available to users (the Possible Spam rule).
A message with a Spam Score greater than 140
will be sent to Company Quarantine and will not be digested (the Confirmed Spam rule).
If the message has a Spam Score less than 100
, no action will be taken (and further Rules will be allowed to proceed).
