It depends on the configuration you want. I never needed to integrate a
windows 2003 server into my Linux/Unix networks. But it is possible.

Perhaps this document will help you:

I think the most important thing is to plan your installation.

Buy some hardware where you can install a ubuntu mail server. If you have
some knowledge about virtualisation you can virtualize your mail server.
It is easier to copy this server to a different hardware afterwards.

Then you have to decide which mail software. (I would recommend postfix
and dovecot. Others will recommend different software.) Setting these up
is as simple as installing all needed packages and answering all the
questions at the installation.

Then you should play around with one or two Unix users on the server and
see whats happening and so on. Regardless which mail software you use, you
have to configure them according to your needs.

Then you have to decide how your user management on the Ubuntu server is
organized. The easiest would be having Unix accounts on the Ubuntu server
and Windows (Active Directory?) accounts on the Windows server.
Disadvantage: you have to create and manage the User on two servers.
Another way would be to use directly the accounts from your Windows
server. But then you need some knowledge about Active Directory and LDAP.
Or read the PDF above.

Then you have to test and test and test! :-)

And then you have to deploy it in your company.


Hope this helps,
