Rated best by our technical support. Excellent performance, very low false positive rate.
Still one of the bests. Give it a try if you need to increase spam filtering performance.
Either the risks are higher than usual or this blacklist is contained by another, higher rated blacklist.
Do not use this blacklist. Either it is no longer operational or it has been superseeded by another blacklist.

Notes

Not finding a popular blacklist in your ORF? Your blacklist definitions might be outdated. Read this KB article on updating them. Check out our Best Practices Guide for the list of currently recommended blacklists.

The above statistics are calculated from anonymous statistics reports sent by ORF clients.Only reports by ORF version 4.3 and newer are used to generate the statistics. Reporting is voluntary and are turned off in a considerable number of installations.

The Spam Rate figure ignores the whitelisted email traffic.This is because outbound emails and internal emails are often included in the whitelisted email figures.
