[ Message body was here ]
--=_mime_boundary_--
The Source-Port field definition is given by [RFC6692].
In the final MIME entity, the local-parts of To and From addresses
are reported unredacted. Since we know that the local parts are PII,
we can reduce the privacy risk by redacting them. In the example,
the report generator could have replaced "users" with "lRLxexey" and
"author" with "RT47aVey" throughout the entity.
If the body of the message is not included, the last MIME entity
would have "Content-Type: text/rfc822-headers" instead of "message/
rfc822".
