For the win.  I recently had some help (thanks alp) in getting
LetEncrypt set up on my (very crusty) Debian web server and it is
working great.  I also use that cert for smtp so now it appears as a
legit cert to web and mail clients because the cert chain goes back to a
CA that is installed in the client.  That way, you don't need to ask
your users to accept a self-published "snake-oil" cert.  Unfortunately,
this does involve US-based infra, but it is run by people we trust (EFF
and IESG).
