  package is intended to have size limits and to throw an exception when limits are exceeded.");

  NOTE: email.utils.parseaddr is categorized as a Legacy API in the documentation of the Python
  email package. Applications should instead use the email.parser.BytesParser or
  email.parser.Parser class.");
