 Not sure if you are using ipchains or iptables. The ipchains setup is under 
/etc/sysconfig/ipchains. You probably need to add an accept rule for telnet 
and smtp (ports 23 and 25 respectively). Something like
ipchains -A input -p tcp -i <external interface> -d <external IP> 23 -j ACCEPT
 Do the same for port 25. Not sure if you need to open these ports for udp as 
well. If you are using iptables you should check the man pages and howto's.
 You also have to allow the services in /etc/hosts.allow. Something like
in.telnetd:	ALL
 See man hosts.allow for details.

					Bye,
