$mail             = new PHPMailer();

$mail->IsSMTP(); // telling the class to use SMTP
$mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
                                           // 1 = errors and messages
                                           // 2 = messages only
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "tls";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 587;                   // set the SMTP port for the GMAIL server
$mail->Username   = "[email protected]";  // GMAIL username
$mail->Password   = "password";            // GMAIL password

$mail->SetFrom('[email protected]', 'First Last');

$mail->AddReplyTo("[email protected]","First Last");

$mail->Subject    = "PHPMailer Test Subject via smtp (Gmail), basic";

$mail->AltBody    = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test

$mail->MsgHTML(true);

$address = "[email protected]";
$mail->AddAddress($address, "John Doe");

//$mail->AddAttachment("images/phpmailer.gif");      // attachment
