    Default Single domain with multiple servers

    Hi,

    Is it possible to use a single domain for multiple mail servers that are located geographically in different countries?

    Let me explain our current scenario.

    Our company has 3 offices in different countries .
    All these offices are using separate mail servers with more than 1000 users

    Country A
    Mail server: company.net
    Users: a1@company.net, a2@company.net, a3@company.net ..

    Country B
    Mail server : company.org
    Users:b1@company.org,b2@company.org, b3@company.org.....

    Country C
    Mail server : company.biz
    Users: c1@company.biz, c2@company.biz, c3@company.biz...


    What we require now is to put all these users under a single domain name , company.com
    How can we use one single domain for all these different mail servers?
    We wish to have separate in house mail servers at each country so that the local mails can be locally delivered.

    What we have to do for this? Please give a solution....!


    Thanks,
    Samihan

    Please update your forum profile with the output of the following information (do not post the output in this thread):

    Code:
    zmcontrol -v
    The solution is in the forums and there are several threads that describe how to do this, did you search first?
    Regards

    In short: yes you can. You can assign a "home-server" for an account at two levels: the level of the account, or the level of the Class of Service. I'd advise you make a separate CoS for each office.

    Thank you Hivos,

    Let me explain the requirement,

    We wish to have separate in house mail servers at each country so that the local mails can be locally delivered.

    We have a basic idea as follows,

    We will register a new domain www.company.com and will point its MX records as

    MX 10 maila
    MX 10 mailb
    MX 10 mailc


    Hence maila.company.com is in country A with users a1@company.com, a2@company.com, mailb.company.com is in country B with users b1@company.com, b2@company.com and so on


    Each server should be aware of its peers and their accounts, For example maila.company.com must know b1@company.com and c1@company.com belongs to mailb.company.com and mailc.company.com respectively.


    So when a mail for c2@company.com comes to maila.company.com, the server knows that its not for my account, it is for my peer mailc.company.com and the mail will be forwarded to mailc.company.com
    Does this plan is possible with zimbra collaboration suite? if its possible how I begin ? Please advise me..


    Note:- As the offices are geographically separated, we have different set of public ips

    Thanking you,
    Samihan

    The situation you describe is quite standard for a multi-server setup. You'll have one master-ldap server at your head-office, possibly a slave-ldap in each branch office, and one mailbox-server per office. All the functionality you describe will work by default.

    Begin by reading the multi-server install guide and do a test setup on a LAN:

    Hi raj,

    We tried the method you mentioned above.. It worked well in our test environment.
    But what we exactly need is to implement zimbra mail server for 12000+ users spread across 4 counties with an average of 3000 mailusers per a country.

    Will you please point out an exact method for us ?

    Thank you ..
