<?php
if ( isset( $_POST['mailto'] ) ) {
    $subject = 'test send mail() from php';
    $from = 'From: [email protected]';
    $message = 'this is mail message.';
    $result = mail($_POST['mailto'], $subject, $message, $from);
    if ( $result ) {
        echo 'done';
    } else {
        echo 'fail';
    }
}
?>

<form method="post">

<input type="submit" value="send" />
</form>   

<?php
	require_once('class.phpmailer.php');
	$mail = new PHPMailer();
	$mail->IsHTML(true);
	$mail->IsSMTP();
	$mail->SMTPAuth = true; // enable SMTP authentication
	$mail->SMTPSecure = ""; // sets the prefix to the servier
	$mail->Host = "mail.thaicreate.com"; // sets GMAIL as the SMTP server
	$mail->Port = 25; // set the SMTP port for the GMAIL server
	$mail->Username = "[email protected]"; // GMAIL username
	$mail->Password = "xxxxxxx"; // GMAIL password
	$mail->From = "[email protected]"; // "[email protected]";
	//$mail->AddReplyTo = "[email protected]"; // Reply
	$mail->FromName = "Mr.Weerachai Nukitram";  // set from Name
	$mail->Subject = "Test sending mail."; 
	$mail->Body = "My Body & <b>My Description</b>";

	$mail->AddAddress("[email protected]", "Mr.Adisorn Boonsong"); // to Address
