MailFrontier was a pioneer in the use of combining multiple spam detection techniques into a single solution to keep your inbox free from junk email.  The use of multiple techniques allows the MailFrontier Desktop system to remain effective at blocking spam even as spammer’s use new and creative ways to subvert anti-spam systems.

Judging Email
"Good” email consists of messages that you desire to receive.  These messages can be from friends and family as well as groups and companies.  Good email can range from a one line message to a newsletter.  It can be a forwarded message, a reply, or contain pictures and links to web sites. 

MailFrontier Desktop develops a profile that is unique to you of the email you want to receive.  Email that fits this profile gets a “free pass” and is delivered to your inbox.  Email that does not get a free pass is examined by the MailFrontier Desktop email protection engine to judge whether it is good or junk.

Junk and Unjunk
The “Junk” and “Unjunk” buttons are helpful in tailoring MailFrontier Desktop to your email likes and dislikes. They work as follows:

The Junk Button:

• Moves the message from your inbox to the MailFrontier Junk Mail folder.
• Adds the sender to your “Blocked” sender list.

The Unjunk Button:

• Moves the message from the MailFrontier Junk Mail folder to your inbox.
• Adds the sender to your “Allowed” sender list.
