1.6 The Body

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 test             <- add
                            <- add
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:
