A single account in our Zimbra 7.1.3 server is having ham messages placed in their Junk folder. Example headers from such a message are...
- X-Spam-Flag: NO
X-Spam-Status: No, score=-2.9 tagged_above=-10 required=4.4
tests=[ALL_TRUSTED=-1, BAYES_00=-1.9] autolearn=ham
and the subjects are NOT prefixed with [SPAM].
As the example above has been autolearned as ham, and the docs indicate that "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 userÃ‚â€™s junk folder" and our negative score doesn't meet that threshold, I'm further confused as to why this would be placed in Junk.
Other non-SPAM messages to other users with lower SPAM scores (ex: -4.1) are NOT placed in their respective Junk folders.
Can someone enlighten me?
