Use single exchange mail server for multiple domains

By magarguy ·
Again, I have another problem.

I have a client who want to use a single mail server for their group of companies with separate domains. Multiple domains need to be combined to use single exchange server.

Can any one be helping me in this situation.

Which Environment ?

by griffon In reply to Use single exchange mail ...

What infrastructure do you have ? Multiple domains within a unique forest or multiple Forests (if microsoft infrastructure)

If you have a single Active Directory Forest, you can install Exchange 2003 or 2007 and serve multiple AD domains.

If you have multiple forests, you could be using an Exchange resource Forest model.
In this scenario, you use an AD Forest to host your Exchange infrastructure (resource forest). Users can be located in other domains/Forests and get connected to this exchange infrastructure. Can you have trust relationship (if Microsoft Infrastructure)?

Domains (AD Domains or SMTP DOmains)

by griffon In reply to Use single exchange mail ...

If you need to host multiple SMTP Domains and your are using Exchange server (2000 or later), you can create recipient policies to hosts multiple smtp domain names as needed. You will need to create also DNS MX records to point to the correct zone and specify the Exchange server responsible for it
