Email Checker for Contact Form 7

I was very frustrated by getting spam bot emails from my website's contact forms.
Then I realized the bots are not using real emails in the contact form.


So filtering invalid emails can solve the problem I taught and it really did.
Now I only get valid and important emails and messages from my website.
