Mozilla anti-spam

My Mozilla spam filter was working fine until lately. I've been getting lots of unflagged spam lately, due to creative lettering. After keeping up the marking as "junk", it now seems my filter is also moving a fair amount of non-spam to the junk folder, including much needed emails regarding employment opportunities. Does any other filter work better? -- Jim Sabatke Hire Me!! - See my resume at http://my.execpc.com/~jsabatke Do not meddle in the affairs of Dragons, for you are crunchy and good with ketchup.
