Estou tentando enviar e-mails SMTP usando o PHPMailer, mas continuo recebendo essa mensagem de erro, tem alguma idéia de como se livrar dela?
Estou tentando conectar via SSL na porta 465.

SMTP -> FROM SERVER: 
SMTP -> FROM SERVER: 
SMTP -> ERROR: EHLO not accepted from server: 

Notice: fputs() [function.fputs]: send of 18 bytes failed with errno=32 Roura přerušena (SIGPIPE) in /home/www/amazonek.cz/subdomains/library/PHPMailer_v5.1/class.smtp.php on line 494
SMTP -> FROM SERVER: 
SMTP -> ERROR: HELO not accepted from server: 

Notice: fputs() [function.fputs]: send of 12 bytes failed with errno=32 Roura přerušena (SIGPIPE) in /home/www/amazonek.cz/subdomains/library/PHPMailer_v5.1/class.smtp.php on line 212
SMTP -> ERROR: AUTH not accepted from server: 
SMTP Error: Could not authenticate.

Meu código:

  require_once('../library/PHPMailer_v5.1/class.phpmailer.php');

        try{
            $mail = new PHPMailer(true);
            $mail->IsSMTP();
            $mail->SMTPAuth = true;
            $mail->Host = SMTP_SERVER;
            $mail->Port = SMTP_PORT;
            $mail->Username = SMTP_USERNAME;
            $mail->Password = SMTP_PASSWORD;
            $mail->SMTPDebug = 2;
            $mail->SetFrom(MAIL_ORDERS_ADDRESS, MAIL_ORDERS_NAME);
            $mail->Subject = 'AMAZONEK.cz - objednávka číslo '.$_SESSION['orderId'];
            $mail->MsgHTML('<b>Ahoj</b>');
            $mail->AddAddress($_SESSION['user']['email'], $_SESSION['user']['name'].' '.$_SESSION['user']['surname']);
            $mail->AddBCC(MAIL_ORDERS_ADDRESS, MAIL_ORDERS_NAME);

            if(!$mail->Send()) throw new Exception($mail->ErrorInfo);
        }
        catch(Exception $e){
            echo $e->getMessage();
        }

Definição de constantes:

define('SMTP_SERVER', 'smtp.ebola.cz');
define('SMTP_PORT', 465);
define('SMTP_USERNAME', '[email protected]');
define('SMTP_PASSWORD', '***CENSORED***');

define('MAIL_ORDERS_ADDRESS', '[email protected]');
define('MAIL_ORDERS_NAME', 'My Name');

Alguma ideia?
