This module is deprecated since version 2.3: The email package should be used in preference to the rfc822 module. This module is present only to maintain backward compatibility, and has been removed in Python 3.

But here is another module which is plone.rfc822

This package provides primitives for turning content objects described by zope.schema fields into RFC (2)822 style messages. It utilizes the Python standard library’s email module.

For installation: pip install plone.rfc822
