forward mail.

[Rob Galloway_1]

Jeff,

Sorry about the slow response had to go home for the night. I have only just logged back in.

Can you clarify a point for me.

What is the hostname of the machine you are trying to forward mail to?
I am guessing at 'co' but I want to be sure that that is not part of your domain name?

As per the question above can you do a nslookup to this host.

this is what I get when I run nslookup.
My server name is diomede and the ip is 172.16.0.1
My domain name is co.fairbanks.ak.us
The addresses that I was given for DNS are 172.16.0.41 and 209.165.150.166

root: /etc ==> nslookup diomede
*** Can't find server name for address 172.16.0.41: Non-existent domain
*** Can't find server name for address 209.165.150.166: Timed out
*** Default servers are not available
Using /etc/hosts on: diomede

looking up FILES
Name: diomede
Address: 172.16.0.1
Aliases: diomede

Hi,

Your forwarding system is 172.16.0.1 which is a private IP. Have your routers in your network been configured in the first place to route traffic from a private IP address (eg. NAT) to the public network?

Can you perform a ping to the mail server you are trying to forward your mail to? If ping is blocked at your firewall, try the following to troubleshoot:

# telnet mail_server_ip 25

See if it gets connected successfully.

Hope this helps. Regards.
