Sender Error on iOS devices

[Will1]

Hi, my TPG email can receive but can't send on both iPhone and iPad. I've tried to reset the pw and still same.

What error (text and codes) do you get? 

Does it happen when using Post Office via browser or email client?

On iPhone and iPad. Post Office (Webmail) is fine. It says user name and password is incorrect.
