**  SAVEMAIL -- Save mail on error
**
**	If mailing back errors, mail it back to the originator
**	together with an error message; otherwise, just put it in
**	dead.letter in the user's home directory (if he exists on
**	this machine).
**
**	Parameters:
**		e -- the envelope containing the message in error.
**		sendbody -- if TRUE, also send back the body of the
**			message; otherwise just send the header.
**
**	Returns:
**		none
**
**	Side Effects:
**		Saves the letter, by writing or mailing it back to the
**		sender, or by putting it in dead.letter in her home
**		directory.
