Start by describing what you did in order to subscribe.

It does leave the loop on NULL or it never gets NULL?

considering that G.fp0 is a stdin:

        xdup2(STDIN_FILENO, 3);
        G.fp0 = fdopen(3, "r");

the way to get stdin to dry out is to redirect it from a file

sendmail ... <email.txt

If you insist on typing your mail in from keyboard, perhaps try
<enter>Ctrl-D<enter> to send EOF.
