[SOLVED] new to Zimbra

[devonps]

Hi,

I've installed Zimbra onto a stand-alone server running Ubuntu 8.04LTS. This server sits behind a router and has a static IP.

I have setup several email addresses for my domain and I can receive mail from external sources to these addresses but I cannot reply back to some of these sources.

I originally tested my mail connection (to/from) using a Googlemail account and was successful with that.

Can anyone point me in the right direction?

Welcome to the forums

Please check /var/log/zimbra.log for the associated postfix error message. This should point us in the right direction for helping you out

[devonps]

ok, here are the entries in /var/log/zimbra.log that contain references to postfix

I know the ntlworld.com domain exists as they are my ISP and I have used them successfully to send/receive mail before installing Zimbra.

Looks like a lookup issue on your server. Please post the following

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomainname mx
dig yourdomainname any
host `hostname` <- note backticks and not single quotes

As your ZCS is on a private IP you will need to setup a Split DNS - Zimbra :: Wiki architecture.

[devonps]

Ok - thanks for the speedy response.

Before I embark on this - will the split DNS approach be hindered by my webserver which runs on a seperate machine, using port 80? The webserver is an Apache webserver.

I currently have port-forwarding setup to route port 80 traffic to my webserver and would prefer to keep it that way.

Once again thanks - time to get reading.

[uxbod]

Do you wish your ZCS installation to be accessible from the Internet ? If so you are going to have a conflict with the port 80 forwarding, unless you have any free IPs ?

Yes I do want it accessible from the internet, and no I don't have any free IPs - that would be too easy lol

I'm hoping to run both servers concurrently.

[uxbod]

Okay so if port 80 is being forwarded to your webserver how you going to get it to ZCS Do you also forward 443 ? if your not using SSL on your webserver you could use ZCS on 443.
