I use formmail.pl on all my websites for the Contact Us form. On one of them, the landing page for my domain sales, I am getting a lot of SPAM form submissions. Has anyone integrated invisible recaptcha into formmail? Or what is the best submission form, free script software to use these days, and then integrate invisible recaptcha into? Here is the contact us form I have up xynames.com I assume I must modify both the html for the submission form and the formmail script. I would like to integrate the recaptcha into my existing SEND NOW button. There is literature on the web about integrating regular recaptcha into formmail, but not invisible recaptcha.
