Custom Email Validation not working

Hi,

I am trying to add a custom email validation in text.php which does not allow any public domain emails.
Not sure what am I doing wrong here, its not working

[email* company-email placeholder “Business E-Mail”]

// Add custom validation for CF7 form fields
function is_company_email($email){ // Check against list of common public email providers & return true if the email provided *doesn't* match one of them
	if(
		preg_match('/@gmail.com/i', $email) ||
		preg_match('/@hotmail.com/i', $email) ||
		preg_match('/@live.com/i', $email) ||
		preg_match('/@msn.com/i', $email) ||
		preg_match('/@aol.com/i', $email) ||
		preg_match('/@yahoo.com/i', $email) ||
		preg_match('/@inbox.com/i', $email) ||
		preg_match('/@gmx.com/i', $email) ||
		preg_match('/@me.com/i', $email)
	){
		return false; // It's a publicly available email address
	}else{
		return true; // It's probably a company email address
	}
}

function custom_email_validation_filter($result,$tag){
	$type = $tag['type'];
	$name = $tag['name'];

	$_POST[$name] = trim( strtr( (string) $_POST[$name], "\n", " " ) );

	if('company-email' == $name){ // Only apply to fields with the form field name of "company-email"
		if(!is_company_email( $_POST[$name] )){ // Isn't a company email address (it matched the list of free email providers)
			$result['valid'] = false;
			$result['reason'][$name] = 'Please enter a valid Business Email Address.';
		}
	}
	return $result;
}

add_filter( 'wpcf7_validate_email', 'custom_email_validation_filter', 10, 2 );
add_filter( 'wpcf7_validate_email*', 'custom_email_validation_filter', 10, 2 );
