无法使用PHPMailer远程连接到我的电子邮件服务器

Question

I'm writing a PHP script using PHPMailer to send automaticaly emails. For test purposes , I've used a Gmail account with an application passsword and everything works fine. When I replace the Gmail account config with my professional email , the PHP connection script keeps loading a while and ends up with this message. the SMTPDebug is set to 3.

2015-11-16 22:43:30 SERVER -> CLIENT: +OK Dovecot ready. 2015-11-16 22:43:30 CLIENT -> SERVER: EHLO localhost

What does this mean ?

Here is the PHP function that Im using to test the connection to the email server

<?php

require('../PHPMailer-master/PHPMailerAutoload.php'); 

function smtpMailer() {
    $mail = new PHPMailer();  
    $mail->IsSMTP(); // active SMTP
    $mail->SMTPDebug = 2;  
    $mail->Host = 'mail.mycompany.com';
    $mail->Port = 587;
    //$mail->Username = "[e-mail]";
    //$mail->Password = "mypassword";
    $mail->SetFrom = "[e-mail]";
    $mail->FromName = 'foxy';
    $mail->addAddress('[e-mail]', 'John Doe');  
    $mail->WordWrap = 50;                                

     $mail->Subject = 'Here is the subject';
     $mail->Body = 'This is the body in plain text ';


if(!$mail->Send()) {
  echo "Mailer Error: " . $mail->ErrorInfo;
} else {
  echo "Message sent!";
}


}

smtpMailer();

?>

Error
