Permission Keys work by providing information to the Spam Filtering Engine on how the email address was acquired by the sender.  As mentioned previously, this is achieved by embedding a unique code, or key at the point of email address acquisition, and then checking any incoming messages for a valid key, thereby ensuring that they are not mistakenly miss-classified as Spam.

If you have ever lost a legitimate message in your junk folder, then this plug in is for you.  Geobytes' Message Keys for Outlook automatically finds and recovers messages that your spam filter has mistaken for spam.

What is it?

It is a new breed of software known as a Spam Filter Companion - it runs along side your existing Spam Filter to correct Spam filter mistakes. It works by inserting unique "keys" in to each instance of your email address, and then checking for the existence, and validity of these keys in incoming messages.  For the technically inclined, Message Keys for Outlook (also referred to as M4Outlook) is a "plug-in" for Microsoft Outlook that implements the client side of an Email Permission Keys System.

What email has your Spam Filter lost today?

Try this.. open your junk folder and have a look. If you don't already check your spam folder frequently, then you might be surprised at what you find. Spam filters lose all kinds of message, most of them go un-noticed, but they all do you harm. Some of them can be devastating.
