Any alternatives to Google Apps for your domain?

I'm specifically interested in webmail service but will appreciate suggestions to replace other components too.

• Microsoft officelive has web pages, email, etc. for your domain.

• Zoho offer a pretty comprehensive range of products, most of which are free for a limited number of users/projects/whatever...

  • Calendar
  • Challenge
  • Chat
  • Creator
  • CRM
  • Discussions
  • Docs
  • Gadgets
  • Invoice
  • Mail
  • Meeting
  • Notebook
  • Office for Microsoft Sharepoint
  • People
  • Planner
  • Polls
  • Projects
  • Recruit
  • Reports
  • Sheet
  • Show
  • Viewer
  • Wiki
  • Writer

  Even though the functionality overlaps, they integrate with Google Apps in some places, so you could have a hybrid solution.

  Harlan : I like but don't love Zoho. They seem to be rather over-extended, and they're substantially buggier than Google Docs. This said, they have a lot more features, and if you're OK working around their quirks, they can be a great solution.

• Yahoo is still alive, at least as for webmail

  From Miro A.

• Zimbra is a good alternative. You can find people that propose to host Zimbra for you on Zimbra Hosting Providers.
