Your logic bomb is here:

my $redirect;
use CGI;
my $query=CGI->new;
print $query->redirect($redirect);
[download]

as various people have tried to tell you: you need to actually have a url to redirect to. Since it's undefined, the browser is being redirected back to the same page. With the result that the form gets submitted as fast as the browser and server can handle it.

However, for your real problem, see Merlyn's comment.

Oh, and when it's working, let me have the real URL, so I can sign up many fake email addresses...
