Best wishes to all ..

I'm getting involved in a project where it is needed the
implementation of networkedition for approximately 2 000 mailboxes ..
In five different locations in my country ...

Required by corporate security that each branch has its
zimbra server itself but these are sincronizen with
server at headquarters .. and the output of the mails to
Internet is made by the headquarters

Words, if the sucusal b send an email to the internet should zimbra
route to the branch (where the ISP) the output of the same ..
should not leave the mail to the Internet from any branch bo
another branch ..

It's good that the primary DNS on the corporate network is in the
Branch A ..

Anyone know how to configure zimbra for multiple replicas
