I'm still having the same issue, even with .top.  Am I missing
something?

                for j in M.top(i+1, 0)[1]:
                    emailMessage = email.message_from_string(j)
                    #emailMessage =
email.Parser.HeaderParser().parsestr(j, headersonly=True)
                    # Get fields
                    fields = emailMessage.keys()
                    # If email contains "From" field
                    if emailMessage.has_key("From"):
                        # Get contents of From field
                        from_field = emailMessage.__getitem__("From")

Is there another way I should be using to retrieve only the headers
(not those in the body)?
