We are using a Zimbra intallation on the version 8.6.0 and have diffuclty with the Spam recognition. It's an installation all on one single server and we collected in the mean time over 1000 Spam mails.
Now we invested time to understand the way how Zimbra teachs Spamassassin new rules and there are two open questions in the process.
- How does Zimbra create the new rules for the Spamassassin?
- Where is the file saved with the rules?
- Is there a way to check if the creation of the new rules worked as designed?
- Is there an other possibilaty why Spamassassin do not learn from the mails which are marked as spam from the Users? They get send to the Zimbra Spam mailbox and get deleted as designed in the night after learning them.
The recognition of mails are very poor and even the same mail from the same adress can be tagged and after a few hours when it comes once more, it does not get marked from SA.
Thank you a lot for your time and help.
