icloud outgoing email not working on iphone 11 pro max.

I have been using the mail app since i bought my iphone 11 pro max in Jan 2020. Never had any problems until a week ago. Now, i am not able to send any mail out. I am able to receive but not send. I have even tried third party apps and still the same, not able to send. I can send via icloud on my laptop but not phone. I have searched and tried everything except deleting all from phone and starting over. Any help is apprecitaed
