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.
Subject: a testadd add This is a one line message.
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:
Notice that our
Subject: header line was carried
through without change:
