I've just installed Centos 4 on an Acer G310 server - everything's gone well except I'm not able to SMTP connect to my upstream mail server (I've installed postfix + MailScanner) - I managed to find sort out the dovecot side of things but SMTP remains quite silent - the maillog shows an attempted connect but then a timeout:
May 9 13:08:45 woking postfix/smtp[7895]: deliver_request_final: send: "connect to mailhost.zen.co.uk[212.23.3.98]: Connection timed out" -1
If I connect manually (telnet mailhost.zen.co.uk 25) nothing happens - no response is shown and I presume if I left things for long enough I'd see a timeout message? Here's the output from netstat -pant:
Do you have the firewall turned on and filtering port 25? If you can't telnet to the remote host port manually then you're getting filtered either on your host or on the remote host.

Nope - no firewall - I've just double checked:
[root@woking ~]# chkconfig --list | grep ip iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off

That only confirms that the service is not configured to auto-start (which I agree, should me it is not running) but you may want to confirm this by running something like 'iptables -L'
