Answer 1

Your Host is incorrect . It should be:
$host = 'mail.gmail.com';
and the code is:
$mail = new PHPMailer();
$mail->IsHTML();
$mail->IsSMTP(); // telling the class to use SMTP
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->SMTPSecure = "ssl"; // sets the prefix to the server
$mail->Host = MailConfig::$Host; // sets GMAIL as the SMTP server
$mail->Port = 465; // set the SMTP port for the GMAIL server
$mail->Username = MailConfig::$Username; // GMAIL username
$mail->Password = MailConfig::$Password;
Note the SMTPSecure line
