This script is sending info to my e-mail box, how can I change to have the message field no mandatory, now you have to fill the message box in the form in order for the form to send the message to my email box, here is the form, and here is the PHP file

you have to validate that the $_POST['message'] field has what you want. i have the script exit() if there is an empty message value (nothing or zero) but you likely want to handle it better than this.

<?php

if(!$_POST) exit;

$email = $_POST['email'];
$message = $email = $_POST['message'];

if( empty($message) )
{ exit('You need to provide a message!'); }


//$error[] = preg_match('/\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i', $_POST['email']) ? '' : 'INVALID EMAIL ADDRESS';
if(!eregi("^[a-z0-9]+([_\\.-][a-z0-9]+)*" ."@"."([a-z0-9]+([\.-][a-z0-9]+)*)+"."\\.[a-z]{2,}"."$",$email )){
    $error.="Invalid email address entered";
    $errors=1;
}
if($errors==1) echo $error;
else{
    $values = array ('name','email','message');
    $required = array('name','email','message');
    
    $your_email = "jhondoe@yahoo.com";
    $email_subject = "Allstate new message: ".$_POST['subject'];
    $email_content = "new message:\n";
    
    foreach($values as $key => $value){
     if(in_array($value,$required)){
        if ($key != 'subject' ) {
         if( empty($_POST[$value]) ) { echo 'PLEASE FILL IN REQUIRED FIELDS'; exit; }
        }
        $email_content .= $value.': '.$_POST[$value]."\n";
     }
    }
    
    if(@mail($your_email,$email_subject,$email_content)) {
        echo 'Message sent!';
    } else {
        echo 'ERROR!';
    }
}
?>

You could try removing 'message' from the $required array

$required = array('name','email');
