    Default [SOLVED] Install without FQDN possible?

    Can you install Zimbra w/o a fully quailified domain name? I know there are lots of posts about the FQDN, hosts file, DNS, etc. but what if you don't have one? Our website is hosted offsite by our ISP, and they put our email into a single account, we use fetchmail (SuSE OpenXchange 4) to get the mail and distribute it. All without a doman name for the email server. Just a local IP address, and a name like 'mailserv'.

    Can I install Zimbra this way as well?

    Regards,
    Scott

    Welcome to the forums

    Why not just use a fake domain name ? ie. mailserver.mydomain.net

    If you use a Split DNS - Zimbra :: Wiki configuration you can set what you like. Once setup, add your actual domain so you can set your from address. Then add a external account to fetch your email, or use fetchmail for multiple accounts, and away you go.

    I tried that, but the install crapped out with the errror to fix the hosts file.

    Here is what I have:

    Code:
    127.0.0.1       localhost.localdomain   localhost       mailserv
    192.168.7.103   mailserv.rci.ca mailserv

    ok. if you can provide the following would help
    Code:
    cat /etc/hosts
    cat /etc/resolv.conf
    dig rci.ca mx
    dig rci.ca ns
    host `hostname` <- note backticks and not double quotes

    Here they are. What does it matter what rci.ca produces? I thought you said I could use a bogus domain?

    Code:
    [root@mailserv zcs]# cat /etc/hosts
    127.0.0.1       localhost.localdomain   localhost       mailserv
    192.168.7.103   mailserv.rci.ca mailserv
    192.168.7.107   phpserv
    192.168.7.105   arrow
    Code:
    [root@mailserv zcs]# cat /etc/resolv.conf
    search 199.246.2.115
    nameserver 199.246.2.115
    nameserver 4.2.2.1
    nameserver 4.2.2.2

    Hello. If you use split DNS as you are behind a firewall, and you have a locally installed DNS server, then your fake domain will resolve where the MX record is for your ZCS installation. I presume 199.246.2.115 is a DNS server from your upstream provider ? This should be your ZCS server. Also, having a search of 199.246.2.115 in your /etc/resolv.conf is also wrong as that should specify which domains to search first ie. rci.ca when you specify a non FQDN.

    That is true. I have tried to setup a Split DNS as per the instructions on the link you provided but it didn't work. I get:
    Code:
    [root@mailserv named]# nslookup mailserv.rci.ca
    nslookup: couldn't get address for 'mailserv.rci.ca': not found

    I have gotten a little further. Now, I am getting this:

    Code:
    [root@mailserv named]# nslookup mailserv.rci.ca
    Server:         mailserv.rci.ca
    Address:        192.168.7.103#53
    
    ** server can't find mailserv.rci.ca: NXDOMAIN

    Here are those files requested earlier, after the attempt at setting up a Split DNS:

    Code:
    [root@mailserv named]# cat /etc/hosts

    192.168.7.103   mailserv.rci.ca mailserv
    192.168.7.107   phpserv

    Code:
    [root@mailserv named]# cat /etc/resolv.conf
    search mailserv.rci.ca
    nameserver mailserv.rci.ca
    nameserver 4.2.2.1
    nameserver 4.2.2.2

    In your details above you do not have any A or MX records for the domain rci.ca. Post the BIND config files you've modified.
