$mail->SMTPDebug = 1; // enables SMTP debug information (for testing)
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Port = 465; // set the SMTP port for the GMAIL server
$mail->SMTPSecure = 'ssl';
$mail->Username = "myid#gmail.com"; // SMTP account username
$mail->Password = "xxxxxxx"; // SMTP account password
$mail->From = "myid#gmail.com";
$mail->AddAddress("hostimf#gmail.com");
$mail->Subject = "First PHPMailer Message";
$mail->Body = "Hi! \n\n This is my first e-mail sent through PHPMailer.";
if(!$mail->Send()) {
echo 'Message was not sent.';
