Heh.  I doubt it, but we can *show* you:  check out the Outlook2000
directory in the spambayes project:

    http://tinyurl.com/2vt5

and especially MAPIMsgStoreMsg._GetMessageText() in msgstore.py there.

PR_TRANSPORT_MESSAGE_HEADERS is a MAPI property (not part of the *Outlook*
object model), and it even took Mark Hammond several days to figure out how
to access it without going thru CDO (Collaboration Data Objects -- yet
another API-on-an-API-on-an-...).

Be forewarned that the exact meaning of PR_TRANSPORT_MESSAGE_HEADERS isn't
defined by MAPI, may contain lines that aren't valid SMTP headers, and can
ne downright strange when looking at msgs handled by an Exchange server.
For msgs delivered via POP3, they're what you expect.  Mostly.
