7.6 Public Folder Scanning
Spamming techniques are continuously evolving and consequently you might encounter instances
when spam still makes it through anti-spam filters to the recipient’s Inbox. Through public folder
scanning, users can manually classify email as spam and ‘teach’ GFI MailEssentials spam patterns to
classify similar email as spam. Emails can also be added to the whitelist.
How it works :
1. When an incorrectly classified email (false positive or false negative)is identified, users drag and
drop the email to the appropriate GFIAntiSpam public folder. For more information, refer to Using
Public folder scanning (page 153).
2. Public folder scanning retrieves emails from the GFIAntiSpam public folders and add to
whitelist/blocklist and HAM/SPAM databases.
The GFIAntispam public folders must be created and configured on the mail server. For more
information, refer to Enabling Public Folder Scanning (page 149).
