I've been using Riseup.net mail service for three years. According to the
official site [1], they support users' privacy and such matters.
There are two ways to register, the first is by using two codes from two
different, and trusted, Riseup.net users; and the second is by stating why
you chose to use their services, beware that the reason must be plausible.
To create an account visit the user's page [2], when requested and accepted,
you can log in using the "riseup.net" email suffix to adjust your email
configuration in the user's page, or simply to check your email using the
mail page [3], I recommend using the Squirrel Webmail within the mail page.
They have XMPP/Jabber support which means that you can chat with your
contacts which use Gmail/Google Talk and many others.

Have a nice day.
Addendum: Google is constantly dropping XMPP/Jabber support.
Joke: Soon enough my contact list will be just me and me in another account.
Do I deserve such thing? :(
