I'm running a multiserver ZCS v6.0.9 install.
As per as documentation :
Is there any way to move these thresholds so that email above 75% is also delivered to junk folder, and never discarded?Zimbra utilizes SpamAssassin to control spam. SpamAssassin uses predefined rules as well as a Bayes database to score messages with a numerical range. Zimbra uses a percentage value to determine "spaminess" based on a SpamAssassin score of 20 as 100%. Any message tagged between 33%-75% is considered spam and delivered to the user’s Junk folder. Messages tagged above 75% are always considered spam and discarded.
Our company policy rules enforces to keep all email, and never delete automatically any message, even if it is a real spam.
Thanks for any help!
