It's free and my only nitpick is that you must open it up and delete it's collection from time to time. I do so as a matter of checking my email.

Downloaded Spamfighter for my Outlook Express 6. It's caught a lot of spam in the past year, but far from all. Sometimes when clicking spam button on an email that it missed I get an error message and the program closes after a wait. Then I have to start it all over. Tonight it shuts down completely when I send a letter to spam folder and I have to restart after every deletion. Yes, I have deleted and reloaded Spamfighter and the problems started again very soon after. Has anyone had problems with this program? Is it just as effective to use the tools that come with OE?
