:True, but the rfc822 module doesn't enforce any of these requirements,
:AFAIK.  So it's really much more of an issue of the module's
:API than it is of the actual RFC.

Sorry, I didn't make my point well. You stated that:

My point, was that rfc822 requires a header, however minimal. (I know it
technically requires one of the following: To, CC, Bcc..whatever, the
point is a header is required.)

The module really doesn't try to enforce RFC822 at all. It
assumes that the programmer will be sufficiently knowledgeable in the
RFCs to use the module correctly.

I can't imagine why anyone would want to use if they only had
a message body and no header. is really written for handling

I guess it is incumbent upon the programmer using the module to check
his data first, and make sure it conforms to the assumptions that makes: namely, that it will be starting to read at a header,
that there will be to newline characters in a row to mark the end of the
headers, and that after that it will be pointing to the message body (if
there is one).
