That would work, but then her example would work too.  rf822.Message
has a __str__() function that returns the header lines.

Which is OK, as long as the resulting line separators work out OK.
Some data will end with '\r\n' and will need to be converted to
'\n', or vice versa.  Actual RFC822 protocol probably says nothing
about that, as far as I know, but the SMTP, POP and IMAP protocols
that carry it are CRLF, also some relatively obscure folder formats;
meanwhile, conventional UNIX mail is LF.
