I've done everything I can think of to get Thunderbird to "learn" what is Junk or Not Junk. It does pretty well tagging spam as Junk. But it also tags legitimate email as Junk. I mark those as Not Junk. I add the addresses to my Address Book. But for the most part the errors continue. It's an annoyance. I can, of course, just ignore the whole thing and click thruough the Junk folder. But I'd prefer not to. Any suggestions as to what else I can try? Thank. you.
