    Default Zimbra installed but I still have major issues

    I recently installed Zimbra 7.2.2 RHEL5 on CentOS5 (all Virtual install). After about 2 weeks of forums and tinkering I was finally able to send and receive my first email through my Zimbra install. Although, I'm so ready to call it complete, I just can’t.

    I still seem to have small issues that are keeping me from completely putting this into production.

    1. I can send mail to multiple mail host (i.e.: Hotmail, my work mail, Verizon.net, etc...) however, when I send to Gmail I immediately receive a mail undelivered message. But maybe an hour or two later the mail reaches the Gmail recipient……

    2. When outside of my network I’m able to reach my webmail and admin console by using my domain name (https://hostname.mydomain.com/zimbra ) and (https://hostname.mydomain.com:7071). I can even access my mail via iPhone: (https://hostname.mydomain.com/zimbra/m ). The issue is when on my local network I can only access either option by using the IP address of the Zimbra server.

    3. Also I when mail is received from my Zimbra server it has an address of (user@hostname.mydomain.com) and I would prefer it were addressed as (user@mydomain.com).
    With all that being said I will give you my network configuration:

    1. My Zimbra server is behind my home router (actually 2 routers) I have the first router in DMZ and the second router handles all port forwarding for my LAN.

    2. I have a static Public IP address through my ISP(Comcast- 23.31.XXX.XXX)

    3. My Domain name is purchased through GoDaddy and the setup is as follows:

    ( A) Host
    host.jpg

    (MX) Mail Exchange
    mx.jpg


    (NS) Name server
    NS.jpg

    (CNAME) Alias
    Cname.jpg


    /etc/ hosts/:
    127.0.0.1 localhost.localdomain localhost
    192.168.0.141 mail.mydomain.com mail

    /etc/resolv.conf:
    search mydomain.com
    nameserver 192.168.0.141


    Host $(hostname):
    mail.mydomain.com has address 192.168.0.141
    mail.mydomain.com mail is handled by 10 mail.mail.mydomain.com.

    Your server is NATed? And resolv.conf on your server is:

    search mydomain.com
    nameserver 192.168.0.141


    where 192.168.0.141 is the servers local IP? That doesn't sound right.

    Ok, I was following the wiki for the bind setup on the split DNS. However, instead of using the loop-back address for name-server I just put the servers local IP itself. Should I change this to reflect the loop-back address of: 127.0.0.1?

    You need to give information about the exact error messages you receive, details are in the log files.

    That would indicate a DNS error somewhere oin your LAN, do the rest of your PCs on the LAN use the DNS server on your ZCS server?

    You were asked during the installation if you wanted to change the domain name, you answered no to that - you should have answered yes and changed the domain name to 'mydomain.com' You can change the domain name via the command line.

    Why do you have two routers? One router provides adequate security and two servers no useful purpose. In fact, you mention that the first router is in the DMZ, how can that be possible? Doesn't the first router get your public IP address? Is it possible to change this configuration to a single router?

    It makes no difference whether you you use the loopback or the LAN IP.

    I'm not sure why you went with CentOS 5, given that the OS is retired and not supported past ZCS7. If you are starting with a fresh installation, you should start on RHEL6/CentOS6, since that is supported with both ZCS7 & ZCS8. In fact, starting with ZCS 8.0.4, CentOS6 is an officially supported OS.

    I started with CentOS 5.8 because for 2 reason. #1- I installed CentOS 5.8 because I was not able to install the Desktop environment of CentOS 6.4 using ESX 3.5. #2-My server is 32-bit and not 64-bit so I was not able to use ZCS 8.0.4 either.

    Zimbra isn't desktop software, it is server software. I'd strongly suggest looking at a new server if you want to deploy ZCS.
