        $mail->Host = "smtp.gmail.com";  
        $mail->Port = 465;        
        $mail->SMTPAuth = true;

        $mail->Body    = "This is the HTML message body <b>in bold!</b>";
        $mail->AltBody = "This is the body in plain text for non-HTML mail clients";


        if(!$mail->Send())  {
           echo "Message could not be sent. <p>";
           echo "Mailer Error: " . $mail->ErrorInfo;
           exit;
        }

        ?>

Answer 1

not sure but try $mail->Host = "smtp.gmail.com" =>$mail->Host = "smtp.google.com"

Answer 2

May be because of fire wall?

If you can't sign in to Google Talk, or you're receiving an error that says, Could not authenticate to server, check if you have personal firewall software installed, or if your computer is behind a proxy server that requires a username and password.

Answer 3

Some servers (especially shared hosting) will block you from using SSL with SMTP, I had the same problem once.

Either change host if you can, try using the default PHP mail() function or send through another mail server that does not require SSL e.g. port 25 not 465.

Something like AuthSMTP would be your best bet for an alternate mail server.
