    Default Single zimbra mail server with multiple domains

    Dear all,

    In our office we are running zimbra OSS 7.1.1 with ubuntu 10.04 64 bit server with the domain somex.com. Our server is running behind the firewall using slit DNS running on the same server. Now our company has registered a new domain called anotherdomain.com.

    I added this anotherdomain.com in our existing mail server using the admin console. Now I can able to send mails to outside domains. But I can't receive from those domains.

    I added the correct MX and A record to point our public IP in the control panel of our domain provider. What else is missing in my configurations.

    Do I have to add A and MX record to the new domain in split DNS configuration. If so please tell me how?

    external mail servers can't find your new mx server

    edit: i mean your new domain mx record

    run some tests at:

    Hi,

    I have a similar requirement.

    My requirement is to have 2 domains.

    My box is 64-bit with 2 NICs.
    I'm behind a UTM box and I have 2 static IPs from different ISPs.
    OS is Ubuntu server 10.04 LTS 64-bit.

    I've configured one domain for now, and its without any hassles, and pretty smooth, on one of the NICs. Necessary and relevant f/w config is done.

    Now, I would like to add another domain to the ZCS using the 2nd NIC.

    My idea is to isolate / segregate both the inbound & outbound traffic. One static IP for each domain.

    Request guidence on this, along with your feedback/suggestions on this idea.

    TIA & regards

    You can add as many domains as you like to the server.

    Why? It serves no useful purpose.

    Thanks Bill,

    Would it not be better if the traffic is seggregated.

    In case, I wish to do such seggregation, how to achieve it. I'm on Ubuntu 10.04 LTS. A newbie to both zimbra & ubuntu.

    Thanks in advance for the inputs.

    Regards
    Venu

    If you want to segregate traffic, you would essentially have to run two instances of zimbra and bind them to different ip addresses.
    You would need twice the cpu power and memory to handle that, not to mention double administration effort, since you need to update and backup both instances.
    You can do that but you really shouldn't.

    Especially binding Zimbra to a single IP-adress ist still a very difficult, frustrating and unneccesary painful task.

    In case you need to have two zimbras running on the same server or even have zimbra running along with other services (apache, mailgate ...) on the same server its still easier to run zimbra inside a VM than to have it run on the real machine cause every zimbra-service binds to every available IP-Adress.

    Zimbra itself recommends usage of ESXi for virtualizing its product (see why is binding to a single IP so difficult?)

    best,
