I just signed up for an account at tuffmail.com. I am impressed by the multitude of setup options available, by the flexibility of the setup and let me say it just works.
Very fast email delivery, easy to setup, the latest Roundcube available, the price is good considering unlimited domains and unlimited email addresses, and the support reply very fast and they are very friendly.
I am glad I found this provider, my primary email accounts are now powered by tuffmail
