I have scheduled many schedulers. Normal mail sending while saving the form is working. Whichever I have set the hooks, If mail sending is there Mail is not going and in scheduler it is getting failed.
The error I got is
ImportError: cannot import name ‘HeaderWriteError’ from ‘email.errors’ (/usr/lib/python3.10/email/errors.py)
but I checked in errors.py and HeaderWriteError is present.

What is the solution for it?
