Hosting email for several internet domains with Exchange 2003

Hi

I want to host a number of customers on our Exchange 2003 server.  I want to be able to host domain1.co.uk, domain2.co.uk and domain3.co.uk.  My default domain would be domain1.co.uk.

I then want to enable some way of getting at their mail.  For instance OWA or POP3.  

What I then need to be able to do is ensure that joe.bloggs@domain2.co.uk sends his mail from joe.bloggs@domain2.co.uk and joanne.bloggs@domain3.co.uk to send mail from joanne.bloggs@domain3.co.uk etc.

My default domain has a mail relay server set from our ISP.

I'm assuming this is relatively simple with Exchange 2003, but my question is how can I achieve that?

Thanks
Simon

Nothing that you have posted above is out of the ordinary.
Each user account just needs to have the correct default email address set on it - that is all.

Thanks Simon

I've already set up the domains to accept mail etc.  Where I thought there would be a problem is how the exchange box would know which domain to send the mail from?

Also, how can I setup the POP3 access?  I've not done that before.

Thanks

If the server is configured to accept email for a domain (ie the domain is listed in recipient policy) then it can send an email from that domain. It is just the default email address on the user account.

There is no concept of knowing what domain the email is sent from in Exchange.

As for POP3, all you have to do is enable the service and start it. The service is disabled by default and has to be enabled in Services in Computer Management.

How does the client application (lets say outlook 2003) know where the exchange box is?  Does it simply use my DNS name?

...and for the authentication, I assume that's simply a user set up in ADU&C?

You configure the POP3 client like you would connecting to any other email server. So you would enter whatever DNS name you are using. For external people you will need to ensure that port 110 is open to the internet.

I would also suggest that you use a generic name for the server - pop3.domain.com and use a host in your DNS. Then if you come to change servers, IP addresses or anything else you just update the DNS entry.

POP3 users are still full users of Exchange, they still require an Exchange and Windows CAL. You still have to create the account through ADUC on the Exchange server.

Thanks Simon, excellent info around the CALs as well!!

One final question, does the same apply to OWA for Exchange and Windows CALs?

Thanks

If they are accessing Exchange, then they need the CAL. Microsoft doesn't make the distinction between OWA, POP3, RPC over HTTPS, PDAs etc.
