The body of a mail message consists of everything following the first blank
line to the end of the file.
When you sent your
sendstuff
file, it contained only a body.
Now edit the file
sendstuff
and add a small header.

This is a one line message.
The
Subject:
header line is an optional one. The
sendmail
program passes it through as is. Here, the
Subject:
line is followed
by a blank line and then the message text, forming a header and a body.
Note that a blank line must be truly blank. If you put space or tab characters
in it, thus forming an "empty-looking" line, the header
will not
be
separated from the body as intended.
Send this file to yourself again, running
sendmail
by hand
as you did before:
%
/usr/lib/sendmail
you
<sendstuff
Notice that our
Subject:
header line was carried
through without change:
