can't ping from email server to firewall

[ubundows]

Hello everyone!

can someone please help me! ... I'm a newbie, and I'm looking after this server which was setup by someone else.

The email server is running fedra core 4, with services like postfix, apache, dovecot, spamassassin, amavis among others.

The firewall in the LAN is running IPCop.

the email server is unable to receive nor send any email outside the LAN nor between the users inside the the LAN.

I tried to ping the firewall from the email server, and it says "Destination port unreachable" I want to fix this first.

Can someone please help me. If you need me to run some commands on the server, I will be more than happy to assist!

cheers

Hi,

Can you telnet your Server on port 25 ? also run chkconfig --list |more to check your sendmail run level. Then check that the Sendmail deamon is running.

I can't telnet to the localhost on port 25. The output is pasted below

Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

Thank you in advance!

What's in /etc/postfix/main.cf (please strip out the comments)?
Any errors in the mail log?
What's in /etc/hosts and /etc/resolv.conf?
What's the output of

hostname -f

?

Here's whats in /etc/postfix/main.cf -> please note, I have replaced our domain name and public IP address with fake ones!
