Mail Filtering Rules (a.k.a Reading the mail that counts)

Intellect has some cool features to help you wade through your e-mail. One of the most useful features to me, happens automatically as mail is received. A small icon of a business card next to an e-mail message indicates that the sender's e-mail address is located in my Intellect contacts list, telling me instantly that it from someone I know and is not junk mail.

Located under the Accounts Menu and the Tools Menu is a option tab for Mail Filters. All accounts have the same set of Rules and Actions. Here are some of my own examples:

  1. Any message that has the word SEX in the subject line I want to have deleted on the mail server. Do not even download it.
  2. Any message that has the word WINNER in the subject line, I want downloaded directly to my Trash Folder.
  3. Any message that has is sent from a hotmail user or a yahoo mail user account, I want downloaded directly to a folder called Filtered Mail so that I can review it later. (These services give alias e-mail addresses to anyone without assuming responsibility, they are often the tool of choice for fraud and spam junk mail, so I am personally wary of them).
  4. How about this one: any message with the words Life Insurance in the subject delete from server :)

White List and Black List of Senders

When we White List a sender we are telling Chaos Intellect to always accept mail that we receive from their email address. As you may already know, we already ignore all mail filters if the sender of a message is located in your address book. However, you may want to subscribe to a mailing list of some kind without necessarily adding the email address into your formal address book.

Black Listing is the opposite. Any mail sent from the sender's email address will be typically sent to your trash can.

Bayesian Filtering

Bayesian spam filters mathematically evaluate email message content to determine the probability that it is spam. Bayesian filters are adaptable and can learn to identify new patterns of spam by analyzing incoming email. This process basically works by creating an 2 exhaustive list of words (Bad words and Good words) and then mathematically analyzing each incoming mail message to determine whether it's contents are more likely to be SPAM or not. Because Bayesian logic is based on learning YOUR patterns we need to help educate it. Your individual results should become more and more accurate over time.

On the mail filters window locate the tab for Bayesian. Check the box to enable/disable the bayesian filtering. Once you have enabled this option, I would highly recommend that you click the AUTOSCAN button. Doing so will randomly select messages that are located in any subfolder under your SAVED MESSAGES folder. This jumpstarts the learning process by teaching the program what you consider to be GOOD messages. Upon restarting Chaos Intellect you should see a new folder on the navigational tree named PREDICTIVE SPAM. This folder is the location that any incoming mail will be automatically deposited that is considered SPAM. We do this so you can review the messages to ensure that they are indeed SPAM.

Training your Bayesian filters is easy. By right clicking on a message in the main screen message list you can either select one of two related menu items.

  1. Bayesian Classify as NOT SPAM - Typically select this option only when a message has been incorrectly sent into the PREDICTIVE SPAM folder.
  2. Bayesian Classify as SPAM - Typically select this option only when a message has been incorrectly sent into your INBOX folder.

We do not have to classify items that are already arriving in the correct folders. The fact that a piece of junk mail correctly arrives in the PREDICTIVE SPAM folder indicates that the teaching that you have provided is working.

After extensive training of your filters you might want to COMPACT your Bayesian Filters to reduce their size. Doing so periodically will remove all the words from both the GOOD and BAD lists that have only ever been used 1 time. I personally do this about 1 time per month or so.
