Email service for small business: something companies can use in combination with Box.com / Dropbox.com or other cloud storage instead of Google Apps. This is not really idea but more of our need: we started using more Box (and Dropbox) instead of Google Drive but we are stuck with email provided via Google Apps. There is no other service on the market as Google Apps email for small business.

(I tried FastMail, Atmail, Rackspace, and none of them is a good alternative).
