Answer 1

By using GMail, your settings might likely not be correct; try these (corrected port and SSL address):
$mail->Port = 465; // set the SMTP server port
$mail->Host = "ssl://smtp.gmail.com"; // SMTP server
$mail->Username = "test#gmail.com"; // SMTP server username
$mail->Password = "1234567889";
Alternatively, use TLS:
$mail->Port = 587; // set the SMTP server port
$mail->Host = "tls://smtp.gmail.com"; // SMTP server
Edit: Remove this line below (You first provide settings to use SMTP, then you tell it to use and send trough sendmail and you put a wrong path in configs. Just stick to one service, use SMTP with above settings (or edit2 below) and see):
Remove:
$mail->IsSendmail(); // tell the class to use Sendmail
Edit2: other option (in case the first answer don't work):
$mail->SMTPSecure = 'ssl';
$mail->Host = 'smtp.gmail.com';
