Junk Mail

I have asked this before.

Very frustrating.

I have mail going to my junk folder.

All the advice I have received, and thank you, is not working.

I have tried all suggestions and nothing is working.

I have no idea why. And, yes, I do know what I am doing and can follow instructions.

Now I have email that has never gone to junk, is not junk, was never junk, going to the junk folder.

I am m missing emails I should not be missing and I should not have to check my junk folder every day for mail that should not be there..

Can somebody please tell me what to do, other than articles on how to fix it, which I have done and the problem persists.....

Would it fix things if I got out of Apple mail, deleted everything and start over?

I am at this point to see what happens....

Thank you in advance for any help or suggestions......
