Alexandre, do you really believe that anyone could "deserve to remain a slave"?

Sure, a server is a single point of failure for the group, and must be carefully configured and protected. It's still much safer than hoping users will protect themselves.

People usually don't want to change mail clients.  Most have no idea how to configure crypto or manage keys.
