How to setup email hosting for clients?

How do I provide hosted email accounts for clients?

Is there a open source alternative to Exchange?

Zimbra is one good alternative to Exchange. There are several companies that sell hosted Exchange products too. Almost all other 'groupware' open source projects are lacking in one way or another. A paid alternative to Exchange is Kerio. Their web client is superior to Outlook Web Access in many ways (as is the Zimbra web client).

Would either one allow for multiple domains?

And that would allow clients to use Outlook or whatever mail client from there locations not associated with my network?
Thanks!

Both products have excellent Webclients. I know the Kerio product has a 'connector' for Outlook 2003 and 2007. It will work outside of your network. The web clients provide a much more integrated experience. At first my clients who use Kerio were dead set against using anything but Outlook, but over time, they've all but completely moved to the web access.

Please look at my previous response. Kerio does multiple domains. Zimbra's paid version does as well. If you want to use multiple domains with Outlook access, each domain would likely require a separate login/profile in Outlook.
