Hi Guys, trying to tighten up the qmail server more:
Can I close any of these ports: not sure waht they may be needed for:
tcp dpt:20
tcp dpt:21
tcp dpt:23
tcp dpt:43
udp dpt:123

IIRC you can close 20 and 21 (FTP), 23 (Telnet), 43 (whois), 123 (NTP).
This is of course unless you use any of these services. FTP can be
moved to a non standard port and will decrease attacks by 99%. 953,
993, and 995 are for secure mail transport.

Run the command to activate your SELINUX rules, or disabled it ...

Have you disabled the SELinux on your Centos ?? Or you have to open some
port through the SELinux.
