ALT-MAIL

Alt-Mail is designed to be simple to install, simple to operate, simple to manage, and simple to customize. A full implementation of Alt-Mail can be set up in under 20 minutes on a $5/month virtual machine, on a Raspberry-PI, or on any similar minimal computing platform... Alt-Mail provides access to uncensored and unmonitored email from behind a restrictive firewall, such as within China.
