Here's the issue.  This message's header was clearly labeled spam (via DNSBL zen.spamhaus) by logsat, but it was forwarded to the email address anyway, and the log file shows no problem.  It should have been quarantined.

Actually SpamFilter did not label the email as spam in the headers due to spamhaus. If that had happened, you would have seen an entry like the following:

X-Rejection-Reason: 12 - 521 The IP is Blacklisted by --

The entry you see in the headers:

X-DN-Spam-Blacklisted-By-DNSBL: (blacklisted sender IP was

was *not* added by SpamFilter.

The question is thus "why didn't SpamFilter check the spamhaus RBL blacklist? Could you then please check the "MAPS Servers" blacklist to ensure you have a list of valid MAPS RBL servers, with the correct trailing suffix (usually ",true") at the end? The list should look similar to the screenshot at:

If you are running SpamFilter ISP "standard" instead of Enterprise, the tab should also contain a valid path+filename to store the list of servers.

The only MAPS Server I have listed is:, true

and the checkbox for "Do not quarantine rejected emails from this blacklist" is UNCHECKED.

Spamhaus is detecting that IP address as blacklisted.  but for some reason, it appears that SpamFilter did not check spamhaus even though its listed in my MAPS server list.

My email server (where SpamFilter forwarded the message to) must have flagged the header, after it checked spamhaus (notice the "sbl-xbl" subdomain instead of the now recommended "zen"). hmmm.....

I am running SpamFilter standard

Could you please zip and email us (at support at the section of SpamFilter's activity logfile for the 20th, from 2AM to 4AM, so we can take a look? Please also include your SpamFilter.ini file and the entire \SpamFilter\Domains directory structure. We don't see other test being performed either, the most likely cause at this point indicating an issue with your DNS server(s). With this data we should be able to find out more info on what is happening.
