Downloaded the new Thunderbird email programme because I started having this problem with my old one, though initially (and for ages) it was fine.

I can't make the junk-filter work, even though I have been into every menu and ticked every possible box. No matter how often I mark an incoming message "junk" it lands in my Inbox, as do the repeat-offenders, and nothing ever ever ever gets shunted through to the spam folder.

This feature always used to work fine in my previous T-bird, then one day for some reason it just stopped. So I copied all the emails I wanted to keep (which I do anyway), ditched it, and downloaded a new one. The new one, an upgraded version, seemed to remember my name and account details - which is fine because they haven't changed - but I have no better luck in training the junk controls. I am not doing anything differently from before, and it worked then. And I've used T-bird for years.

Is it me or is it It? And what do I do? Waaahhhhhh -
