Yes, and likely so can the ISP, but you first need to work out which is doing the filtering here.
Option 1: TBird downloads email from your "Inbox" at the ISP and decides some are spam and moves them into a junk folder. Option2: Your ISP decides some are spam and moves them to a junk folder on their server, TBird then downloads both the Inbox and junk folder.
Training TBird will only help with Option 1.
Option2 feels like it might be what's happening. (Who is your ISP? - or who hosts your email, if different.)
it's that the spam folders do not show that they have any emails in them and I want it to.
If it's option2, then that'll be because TBird isn't downloading the junk folder until you open it.
I do ask it not to junk any emails from addresses that are in my contact list.
TBird can see your contacts, but your ISP cannot (unless they are somehow synchronised). So if it's option 2 then your contacts in TBird are irrelevant.
