how to solve this warning in gmail…???

Is it because you’re using the form-fillers name as the “from” address? Does your mail server allow that?

You might want to look at using a library such as PHPMailer instead of the built-in mail() function.

Slightly O/T, but what’s the point of copying the $_POST array to another one? I don’t see that you use it anywhere.

this is just a HTML boilerplate. you can add your class and modify with your website design.
