You can choose to believe that or not. I seem to recall that you have very occasionally made helpful suggestions - maybe I am confusing you with someone else. I give you the same answer - if you believe the TASK of postfix is difficult to understand, explain why. BC hasn't answered this, and I very much doubt if KK will either. As I see it, the principal task of postfix is to take in email arriving at port 25, and convey it to one or more destinations. In my experience email has been working without problems for as long as Unix has been running, long before system administrator exams were invented. It is not necessary to understand how the internal combustion engine works in order to drive a car; and there is no evidence that those who do know make better drivers. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
