I'm don't quite understand what you mean, is it that people can put in anything into the email box and it still works?

Thanks Rookwood, I should point out that the script shared on the page you link to does not actually connect and check if the email address really exists, it simply looks for patterns in a given string to see if it has the right format to potentially be an email! I'm not sure it's possible to truly say if an email exists in many cases. This tutorial helped me set up a verification system for my website, you may find it useful!

Thanks sparks! 

@Rookwood: Thanks as well!
