hello guys sorry for asking you too many silly questions , but its just bcoz i want to know more about qmail so these questions just keep popping up , how qmail will send the message from one domain say a [EMAIL PROTECTED] to someother domain say [EMAIL PROTECTED] when DNS comes in to the picture , is qmail it self starts query authorative dns server for that domain or its a job of some other programme bundled with qmail-1.03 thanks once again , with warmest regards Prashant Desai
