How do I find the reason an email was blocked as spam. A pile of emails got blocked by the Spam filter. This is an extract from the /var/log/zimbra.log log files. Note. This is from a fetchmail script downloading from remote servers and re-submitting to the zimbra server

Where can I get more details information from?
