Sorry for that. I'm new to open source contribution.
While using the email field validation. It return invalid email when white space is attached to the email.
Eg "david@gmail.com "

But has no issues when the white space is removed. Eg "david@gmail.com".

What I did locally was to overing the call method in the Email class validator. Then remove the white space

class Email(Email):
    def __call__(self, form, field):
        field.data = field.data.strip()
        super()__call__(form, field)

It worked properly, locally. Then I decided to contribute.

Maybe you can help fixing it. Thanks!!

I think this is not needed. You should be able to achieve this with filters.

>>> import wtforms
>>> class F(wtforms.Form):
...     email = wtforms.EmailField(filters=[str.strip])
>>> f = F(email=" email@mydomain.tld ")
>>> f.email.data
'email@mydomain.tld'

Thank you anyways 🙇
