Poco Junk Mail FAQ - Positiioning the Junk Mail Filters

Q: I see that Poco provides the ability to position the junk mail filters with respect to the other incoming message filters. Why might I want to do this?
A general rule is to keep the junk mail filters at or very near the end of the list. Mine are not at the very end but that's because I'm running a very heavy duty script on some of the messages that make it past the junk filters to perform additional tests to see if I should classify the message as junk. Other than that there probably aren't too many reasons why you would want to have the junk mail filters before any regular filters.
