If you check your /opt/zimbra/log/spamtrain.log file, and you see this:
20190429234505 Cleanup skipped: mail.example.com is not a spam/ham cleanup host.
Check the following:
zmlocalconfig | grep zmtrainsa_cleanup_host
If nothing returns, or if the setting is false, do the following.
zmlocalconfig -e zmtrainsa_cleanup_host=true
Just remember, if a Zimbra server is running the Spamassassin service, zmtrainsa_cleanup_host must be set to true.
