How can I get text of the body (payload) of an email?

Funny, I recently undertook the same task. Here's my solution:

msg = email.message_from_string(foo)
x = sha.new()
for line in email.Iterators.body_line_iterator(msg):
    x.update(line)
hash = x.digest()

This very cool iterator returns every body line, but skips all the headers,
including the headers present in each sub-part of the email. If you only
want plain text parts, you might combine this iterator with
email.Iterators.typed_subpart_iterator().
