Greetings all, Im a new member. I have a problem with my postfix installation. I followed The Perfect Setup CentOS 4.4. Everything went ok up until the point where i have to "telnet localhost 25", i just hangs there. (Because this is to confirm that postfix can is working) ***** Here is my scenario: My server has 2 NICs, eth0 connected to ADSL modem, eth1 is for our private LAN. I realized that the guide does not show anything about "/etc/hosts" or "/etc/sysconfig/networks" i think i have to put some entries here but i dont know how. And how to configure iptables (for the 2 NICs to communicate with each other) for my users to fetch their mail from the server using outlook. Can anyone help me out since ive been trying to set it up for 2 week but to no avail... Thanks in advance..
