I saw this a few times when I was setting up a custom deliver script.
When I accidentally printed the message to stdout instead of the deliver
process's filehandle, I would get empty messages.

Basically, my script had perfect protocol interaction, it just didn't
supply any data.  In other words, I had rfc821 working perfectly but no
rfc822.
