May I know where is the config to control and allow me to telnet > mylinux 25 from other hosts?? Two things ya gotta do: 1) Open port 25 to the outside world on the iptables firewall. The file to modify is /etc/sysconfig/iptables. You'd then restart the firewall with "service iptables restart" (no quotes). 2) modify your sendmail config. I don't do sendmail, I do postfix. somebody should be able to help you there.
