With output I meant _output sent to the browser_ -- i.e. printed to
stdout.  In your script, you're just printing a message to SENDMAIL.
Sending this mail is considered just a "side effect" CGI-wise.  You
still have to generate some HTML content to be sent to the browser.
IOW, after your "print SENDMAIL <<"end_html"; ..." statement, add some
code to send HTML content to stdout.  Or, use HTTP status code 204. 
To start with, however, it's probably easier to just generate any page
to be shown in response to submitting the form... :)
