Looking to have a form/forms built with captcha before allowing to submit the form online to our email address with the information filled out online by users. This page needs to be fully encrypted and impossible for anyone to abuse this page. Reason being, can provide the page in php that works, yet tons of spam bots emailed to it and through it to commit spam to someone else using our sites and ultimate had to remove because hosting was getting complaints. It can also be done in html, open to whatever works best and is most secure and impossible to abuse. The page needs to be open source, since from time to time need to update info on our end, with more variables and different or additions to email address where form info needs to be sent.
