I have installed Fedora 6 and followed the step-by-step installation but when i run the command # telnet localhost 25 the following result displays: [root@safariktech ssl]# telnet localhost 25 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. 220 safariktech.com ESMTP Postfix 421 4.4.2 safariktech.com Error: timeout exceeded Connection closed by foreign host. what does it mean? by the way, i have fedora 4 installed also and serve as firewall.
What's the output of netstat -tap? What's in /etc/postfix/main.cf (please strip out the comments) and /etc/hosts? What's the output of Code: hostname -f ? Did you disable SELinux on your system?
