PHPMailer - SMTP Error: Could not connect to SMTP host

问题

I'm trying to send email using PHPMailer. When I tried sending the email from gmail account, it works perfectly fine. However, I would like to send the email from my own SMTP, but there seems to be an error. What could be the problem? Please help me. Thank you.

Using smtp.gmail.com :

$mail->SMTPDebug = 3;
$mail->isSMTP();                                      
$mail->Host = 'smtp.gmail.com';                 
$mail->SMTPAuth = true;                               
$mail->Username = 'myemail@gmail.com';                 
$mail->Password = 'password';                               
$mail->SMTPSecure = 'tls';                           
$mail->Port = 587;

Using mail.distech.com.my :

require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->SMTPDebug = 3;
$mail->isSMTP();                                      
$mail->Host = 'mail.distech.com.my';                    
$mail->SMTPAuth = true;                               
$mail->Username = 'myemail@distech.com.my';                 
$mail->Password = 'password';                           
$mail->SMTPSecure = 'tls';                            
$mail->Port = 587; 

$mail->From = 'myemail@distech.com.my';
$mail->addAddress('amalina@distech.com.my');     
$mail->Subject = 'Test';
$mail->Body    = 'Test message';

if(!$mail->send()) {
   echo 'Message could not be sent.';
   echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
   echo 'Message has been sent';
}
