PHPMailer SMTP connect() failed not work for other address

Question

I use phpmailer to send messages. I used with my Gmail account to be sent ok, but When I change account on other (new account) I gets an error.

Message could not be sent.Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

Username and password are correct. I must something change in my mail settings?

Code:

<?php
require 'mailer/PHPMailerAutoload.php';

$mail = new PHPMailer;

//$mail->SMTPDebug = 3;                               // Enable verbose debug output

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'user@gmail.com';                 // SMTP username
$mail->Password = 'pass';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465;
$mail->Host = gethostbyname('smtp.gmail.com');

//Set the encryption system to use - ssl (deprecated) or tls
$mail->SMTPSecure = 'ssl';                                   // TCP port to connect to
$mail->CharSet = 'UTF-8';

$mail->setFrom($_POST['email'], 'Wiadomosc');
$mail->addAddress('xyz@gmail.com', '');     // Add a recipient

$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Wiadomość ze strony Akademia Uwodzenia';
$mail->Body    = 'Imię: '.$_POST['imie'].'<br>Nazwisko: '.$_POST['nazwisko'].'<br>Wiadomość: '.$_POST['wiadomosc'].'';

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

I have openssl. Sending works for my gmail account. After the data is changed to another account - company account. The code is not working.
