wrote a little Mail Adresse Validator in Python. use it, modify it, like it … best practice for python is to use a virtual env like Poetry (or virtualenv) and add the “email-validator” module like this:
poetry add email-validator Code few lines of code …
#!/usr/bin/env python3 from email_validator import validate_email, EmailNotValidError ok=[] nok=[] emails = [ "my+address@mydomain.tld", "hans@dampf.ch", "gott@welt.net", "adsf@asdf.com", "asf.asdf", "franz!mueller@abc.com", "asdf@asdf.adf" ] print ("\nMy Little Mail Validator\n") for email in emails: try: # Validate.
