RE: Getting TLS working

I'd messed up the permission on ~/.authenticate/private. It's now trying
to start TLS and prompting for a password, which is further than I'd
managed to get before, but it doesn't seem to be quite working yet.
There's a lot of encrypted traffic and what seems to be a 554 response.

At the client end I'm getting SMTP_EV_NO_CLIENT_CERTIFICATE. As it's
prompting for a password, I'm guessing that it doesn't like the password
I'm giving it.
