How can I tell Junk is actually being filtered?
There are three things to check to verify MailFrontier Desktop is doing its job.
1) Is MailFrontier Desktop launching correctly when you open Outlook or Outlook Express? You should see the MailFrontier Desktop toolbar with the Junk and UnJunk buttons visible.
2) Is spam still remaining in your inbox? MailFrontier Desktop should make an immediate impact on the amount of spam that remains in your inbox.
3) All mail filtered out by MailFrontier Desktop is sent to one of three folders, the MailFrontier Junk Mail folder, the MailFrontier Challenged Mail folder, or the MailFrontier Phishing Mail folder (within the MailFrontier Junk Mail folder). Check the MailFrontier Junk Mail folder to see if MailFrontier Desktop has moved any mail to the Junk folder

How do Outlook Rules and Outlook Express Message Rules affect the operation of MailFrontier Desktop?
Currently, MailFrontier Desktop filters email as it enters your inbox. If you use Outlook rules to send email to folders as it is received, MailFrontier Desktop will not see the email and, therefore, will not filter it.

Can I have other anti-spam programs installed at the same time as MailFrontier Desktop?
MailFrontier Desktop may not operate correctly when installed on a machine that already has an installation of a different anti-spam solution.  Both products will be competing for mail client resources, which can result in neither product operating properly. MailFrontier recommends uninstalling other anti-spam products before installing the MailFrontier Desktop.

Will MailFrontier Desktop filter more than one email account?
MailFrontier Desktop will filter multiple Outlook and Outlook Express Inboxes. All mail must arrive in a default “Inbox” folder. This does NOT include user created folders or sub-folders. Any Outlook Rules that are used to move messages out of a default “Inbox” folder after arrival might prevent MailFrontier Desktop from scanning and filtering these messages.

You are able to set the number of days mail sits in both the MailFrontier Junk Mail and MailFrontier Challenged Mail folders.Double-click on the red MailFrontier Desktop “M” icon located in your system tray (bottom right of screen). Click on the “Settings” option.
Here you will see the Junk Folder Settings field that allows you to determine the number of days that mail remains in the folders before being sent to your Deleted Items folder.

What does MailFrontier Desktop do with the mail it filters?

Known or suspected junk mail messages are moved to either the MailFrontier Junk Mail folder or the MailFrontier Challenged Mail folder. Possible Phishing messages are moved to the MailFrontierPhishing Mail folder.  The MailFrontier Junk Mail folder contains all email that MailFrontier Desktop has determined to be spam.  Any email that MailFrontier Desktop challenges on your behalf is held in the MailFrontier Challenged folder.
The MailFrontier Phishing Mail folder contains all email MailFrontier Desktop has detected as phishing.  MailFrontier strongly recommends you do not reply to these messages directly.
