Note that parts are not required to be named.

text/plain

The body's name is MTA-dependent.  A safer way to check for this would be
to look for messages which have a text/html part, but no text/plain part.
(You wouldn't want to look for text/html as the only part because it
could have attachments, but still lack a plaintext version of the body.)
