Email not sending on iPhone

Hi, I am having a very big problem with the mail app in iOS 16. I have two emails set up and when I reply to a email, it can’t send, it just goes straight to my outbox and a error message says server not found. I tried everything, I looked to see if my server for the emails is turned on and it is and I also re-added my two emails again and it still did not fix the problem. I did not change anything about my two emails since I had iOS 15. In iOS 15, did not have these problems but now I do. This is definitely a iOS 16 problem.

Same thing happened to me. After sending, I was unwittingly tapping Undo Send at bottom of screen by accidentally touching or swiping up to exit before mail had a chance to send. Undo Send option is on by default. There is a minimum 10 second delay to mail actually being sent, even after you hear the whoosh. Go to Mail preferences, scroll down to very bottom > Send > Undo Send Delay > Turn Off or choose 10/20/30 Seconds.
