FormMail Clone is clone of Matt Wright's FormMail under a less restrictive license. It should behave almost exactly as FormMail.cgi, but it is completely written from scratch so there might be a few minor visual differences.
The Actual Script is here: http://yourdomain.tld/cgi-sys/FormMail.cgi
The documentation for Matt Wright's FormMail.cgi might be helpful if you have never used FormMail before. It is available here. Please note that the cPanel developers are not associated with Matt Wright's Script archive in any way.
