mi codigo es el siguiente :

try{
SMTPSession session = new SMTPSession(host,puerto,usuario,clave);
SMTPMail mail = new SMTPMail(remitente,usuario,asunto,true);
mail.setMessageText(mensaje);
mail.addBccAddress("xxx", correo);
session.sendMail(mail);
intError=0;
}catch(Exception e){
System.out.println("Error envio mail "+e);
strError="No se pudo enviar el archivo, Comunicarse con el Administrador ";
e.printStackTrace();
}

porfa, si alguien me puede ayudar con este tema, tambien instale el servicio SMTP en linux pero igual me sigue saliendo el error.
