Email regex does not match user.name-secondname@domain.com

Email regex does not match user.name-secondname@domain.com oder an other Adresse with valid "-" before @

It should be

def _is_email(self, email):
    pattern = r'[\-\.\w]+@[-\.\w]+\.\w+'
    if re.fullmatch(pattern, email):
        return True

Same error here with user.name@twopart-domain.com

On gmail you could also have an email address like user+label@gmail.com, so character '+' should be added to the regex
