I am having a problem on my LM 7.1 server running postfix. I need another pair of eyes to help me with this. I am getting entries in the /var/log/main.info like: Dec 2 21:15:17 server1 postfix/smtp[21898]: connect to ASPIRIN.DII.utk.edu[128.169.76.123]: No route to host (port 25) Dec 2 21:15:20 server1 postfix/smtp[21898]: connect to MAILHOST.CAS.utk.edu[128.169.76.44]: No route to host (port 25) which seems to indicate a routing problem and not a postfix problem. Also: [root@server1 mail]# telnet mailhost.cas.utk.edu Trying 128.169.76.44... Connected to mailhost.cas.utk.edu. Escape character is '^]'. Connection closed by foreign host. [root@server1 mail]# telnet mailhost.cas.utk.edu 25 Trying 128.169.76.44... telnet: Unable to connect to remote host: No route to host As you can see, I can telnet the host but NOT on port 25! Anyone have an ideal why this fails? TIA, Bill This is not an ipchains rule blocking output to port 25.
