Linux Mail Server Setup and Howto Guide

Hi, the experts

I followed this article http://www.linuxmail.info/post…..-centos-5/ and everything works great until I configured the postfix to run in a chrooted jail.

I got a "temporary lookup failure" while doing a test from telnet. (i'm running postfix on CentOS v5.4)

I believe that I have missed something in /var/spool/postfix. But googled a couple of days and got no findings.

BTW, I have copied /dev/random and /dev/urandom to /var/spool/postfix/dev

Please help.

Thank you
