When I add a new domain on the control panel of Dreamhost, Google’s logo catch my eyeball.
Now users can Set up calendar.domain.com, docs.domain.com, sites.domain.com, and start.domain.com, free with Google.
And use Gmail as email provider.
And the last is Google Page Creator for hosting. All free.
If you want better email service, not he simple web mail interface, I suggested you use Gmail. It is part of Google Apps services. Google Page Creator is good for new site owner without HTML knowledge. It is easy to use and similar to word processor.
