Need help with iCloud set up on Mac Mail Client

hi thanks for you help. I had a long day of issues with my icloud configuration on my Mac Mail. Suddenly (with no changes on my part) there were issues with emails going out. I followed the protocols below. Is there an issue with my AUTHENTICATION choice? I tried external tps but that didn't work, but Apple Token is what is working). I have the box checked for keep sent emails. I can't figure this out and it's so frustrating. I have a new Air Laptop.
