K9 - Expert Guide - Quick Start

For each POP3 account in your POP3 email program that you want to work with K9...

• Change the POP3 server port to 9999.
• Change the POP3 server to 127.0.0.1.
• The POP3 account user name should be changed to incorporate the original POP3 server, port and user name values into one long string, separated by a "/" character.

Here's an example:

Suppose your original account user name value was robin and the original POP3 server was pop.west.cox.net and the original POP3 port number was 110. The new user name entry would now look like

• pop.west.cox.net/110/robin

If your user name happens to contain the character "/" you can use a different character but (a) make sure you use the same character to separate the different parts and (b) change the delimiter character in the Configuration tab in K9 to match the character you chose.

• The password field remains unchanged.
• Create a new Spam folder in your email program. This is where emails marked as spam by K9 will end up.
• Create a rule in your email program to automatically filter emails containing the special marker that K9 places in spam emails into the new Spam folder you just created. You can choose from one of two basic methods that you want K9 to use when it has classified an email as Spam from the Mark emails as Spam by... section in K9's Configuration tab. Outlook Express has rather limited filtering capabilities so for this you should keep the default option of placing the word [Spam] in the email's Subject. If your email program can filter on any header line you should select the Add the following email header line option and create a filter to look for that header line.
• K9 is now ready to use.
• K9 will inevitably get things wrong when starting out. To re-classify a mistaken email open K9 to the Recent Emails tab, highlight the message(s) to be re-classified and click either the Good or Spam toolbar button to force the email to be Good or Spam accordingly. By this method K9 will learn over time.
