Who'd do the configuration? If a techie will do it, I'd suggest a Yubikey
with the OpenPGP applet, just one touch to sign (don't remember which exact
software that supports it, though).

If they do the configuration themselves - OpenKeychain on Android with K9
Mail. That's the only software I can imagine a crypto newbie would tolerate
setting up.
