Configuring IMAP/SMTP after IPCop addition

[Tekime]

Hi all,

I've run into some problems reconfiguring one of my boxes, I'm really hoping someone can throw me a little advice as this box is running my IMAPD/SMTP server and this account is pretty important for me.

Let me give a little info on the situation. I added an IPCop box to my network last night. Previously I had a Slackware box running as a firewall, NAT, IPMASQ, FTP, web and ssh server. Now I have IPCop installed and configured as such:

Green: 192.168.1.1
Orange: 192.168.200.1
Red: DHCP (cable modem)

Now the Slackware box has been reduced to just the web, ftp and email server. httpd, ftp and ssh work fine but IMAP/SMTP are giving me major problems.

I think this has something to do with my hostname configuration, I just can't put my finger on it though. I am configuring a static IP on the web server of 192.168.200.10 and I am hosting the domain fury-tech.com.

I seem to be able to check my mail OK, but none of the test messages I have sent to that address have been deliverable.

nslookup fury-tech.com gives me connection timed out

Here is my /etc/hosts file:

# For loopbacking.
127.0.0.1 localhost
192.168.200.10 fury-tech.com fury-tech

And I'm sure there is more.

I ran netconfig in Slackware and I think it replaced some files. My /etc/resolv.conf looks like this:

search fury-tech.com

Whereas before it was configured with my ISP's DNS servers.

Please let me know if there is any more info I can provide, and any help would be so greatly appreciated!!!

make sure port 25 is forwarded to the mailserver (SMTP) and the domain is set up as your external one on the server.

e.g.

my domain: viperlin.gotdns.org


i have a machine with the DNS name viperlin.gotdns.org in my network hosting all servers including SMTP.

from there look @ smtp domain settings in config files.

good luck

25 and 143 are forwarded. Can you expand a bit on setting up domain as the external one on the server? Does this just amount to specifying the IP and domain name in the hosts file?

Thanks for the input. I set this box up over a year ago so I think I'm forgetting much :(

my registered domain is viperlin.gotdns.org that points to my IP address.


my servers hostname is "viperlin.gotdns.org"
(look how to set the hostname in slackware)
it usually consists of it written in /etc/hostname
and a line in /etc/hosts:

192.168.0.7 viperlin.gotdns.org



then it should work by default, or did for me (i use Gentoo)

Yeah I have that set but still no luck :(
