Junk / Spam filter filtering my own email and others unwanted

My junk filter is not working properly. Too many emails are ending up in the local JUNK folder. Even my own email address is affected. When I reply to an email, Thunderbird moves that email to the Junk folder. I marked it as NOT junk several times and then moved the affected emails to the correct inbox and even deleted the training data from the junk filter. Nothing so far :(

Can I reset the Junk filter settings completely somehow? I don't want to delete Thunderbird from my PC and install another email-client, but the daily junk-sightings takes too much time, as I'm working with 4 accounts in TB.

This tickbox lets you select from one of several spam filter products. Spamassassin is provided by some ISPs and can assist you in checking spam, but I think it's only available to you if your ISP has it. Spampal is another product (free) that you can download and use and I have heard excellent results from people use POPfile.

I did that. That's what I meant with "and even deleted the training data from the junk filter". That took no effect :(

Is there any file containig that, which I can delete manually?

Delete training.dat from within your profile. That should do it.

I deleted the trainig.dat file. After I meant some days all should be working fine, I replied today to an email, where I was in cc: and so replied also to me. And Thunderbird moved my own email into local junk-folder :(

I'm at the end of my patience and think really about deleting TB from my system and change to another email-client.

Well, it might be that TB thinks an email that contains the same email address in both FROM and TO lines might be junk. But that's just my guess.

Might be. Could be plausible. BUT: it started sometime in the past (I don't remember when). At some point I realized that I ended up in junk/spam myself. I occasionally send myself reminders when I'm on the go and one day I missed them and then found them in the junk.

It wasn't like that before. Marking junk in the local junk folder as NOT-junk and manually moving it to the correct inbox also has no learning-effect.

Question: I just checked my settings in all accounts for junk and they are such that "trust an external junk header filter" is checked and then it says "spam assassin". Is it maybe because of that? Are there better ones? Especially for the German-speaking area?
