I think I need to reinstall Mail so to speak. How can I do this? What is wrong is that when I upgraded to 10.4.3, JunkMatcher, the plugin for Mail stopped working. That is, it stopped filtering all of the junk mail and would just leave it all sitting in my inbox. I uninstalled it, but Mail still wouldn't filter any of the junk mail. When the latest version of Junkmatcher came out, I installed it, but Mail still refuses to filter anything. It labels spam as junk mail, but it won't move it to the junk mail folder. And yes, I do have the option for it to do that checked. Any help would be appreciated. I tried moving to Thunderbird for awhile, but it is too unstable to use, so I want to use Mail again, but I just get too much Spam a day to use it unless I can get this working again. Thanks!
