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 Your blacklist definitions might be outdated.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.
