 2015-04-21 07:06:52    SMTP connect() failed.
 Mailer Error: SMTP connect() failed.

and my code

$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1; 
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
$mail->Host = "smtp.gmail.com";
$mail->Port = 587; // or 587
$mail->IsHTML(true);
$mail->Username = "[e-mail]";
$mail->Password = "pass";
$mail->SetFrom("[e-mail]");
$mail->Subject = "Test";
$mail->Body = "hello";
$mail->AddAddress("[e-mail]");
if(!$mail->Send())
{
echo "Mailer Error: " . $mail->ErrorInfo;
}
else
{
echo "Message has been sent";
}

at end it's better to know i test tls & ssl with port 465 & 587 but....
