What exactly: zimbra.domain.com or domain.com?

OK, so I went through the problems with DNS, MX, etc. Everything was fixed, and my DNS records look as follows:

d0main.com. NS Default ns1.d0main.com.
d0main.com. A Default 00.0.000.000
ns2.d0main.com. A Default 00.0.000.001
ns1.d0main.com. A Default 00.0.000.000
zimbra.d0main.com. A Default 00.0.000.001
www.d0main.com. CNAME Default d0main.com.
d0main.com. MX 38400 10 zimbra.d0main.com.

And my /etc/hosts file:

127.0.0.1 localhost.localdomain localhost
# Auto-generated hostname. Please do not remove this comment.
00.0.000.001 zimbra.d0main.com zimbra

During the installation, I had the following error:

DNS ERROR resolving MX for zimbra.d0main.com
It is suggested that the domain name have an MX record configured in DNS
Re-Enter domain name? [Yes]
Create domain: [zimbra.d0main.com] d0main.com

So I typed "d0main.com" instead of "zimbra.d0main.com" as was suggested here: [SOLVED] DNS Error Resolving MX.

Installation was successful, but the login page was on... d0main.com, not on zimbra.d0main.com. Why? I turned off Apache before installation. Perhaps I should remove it and let Zimbra install it? Also, there was on port conflict detected during the installation.

Edit: It was suggested to install Apache on different port: http://www.zimbra.com/forums/mobilit...tml#post205980. Would that solve the problem with this? But then again, Apache was turned off and there were no conflicts with ports.

When your domain is "mycompany.com", the Zimbra installer likes to set the default domain to the fqdn of the Zimbra server, e.g. "server.mycompany.com".

Most folks aren't interested in using a domain called "server.mycompany.com" and never set up DNS records for it, so the installer complains there is no MX record for the domain and suggests changing the domain.

What we have found to be the easiest thing to do is as follows:

1. Configure the installer to use e.g. "mycompany.com" as the default domain.
2. After the installer completes and Zimbra is running, add the alias domain "server.mycompany.com" to the domain "mycompany.com".
3. Finally, check things like the From: address for notifications and change them from things like "admin@server.mycompany.com" to "admin@mycopmany.com".

(Probably I don't need to say this, but just to be absolutely 100% clear you should use your own company's domain, not the example "mycompany.com" above!) :-)

Hope that helps,
