Oops..  I know why I said that:  It generally isn't "safe" to use non-printable
characters because

The end-of-line marker can vary from system
The interpretation of TAB can vary

etc..  All of which are open to interpretation during the SMTP
conversation.  In fact, the end-of-line marker used during SMTP is
supposed to be CRLF for *all* messages, not CR, not LF .. CRLF.
(See RFC-822 section 3.3 for the EBNF of a message ..)

You gotta admit though.  Even if ^A^A^A^A is valid for a message
it's an awfully unlikely string as opposed to "From" occuring at
the beginning of the line..  I still prefer mh's way of keeping
messages in seperate files.
