Which is fine, the STARTTLS stuff isn't great if you ask me, as you can't
just put an SSL wrapper like you would for POPs or IMAPs

In your case, you should be able to do something like this:
stunnel -p /etc/ssl/certs/stunnel.pem -d ssmtp -P /var/run/stunnel.ssmtp.pid -l /usr/sbin/exim -- exim -C /etc/exim.conf.auth -bs

I unfortunately haven't had the time to look at the SSL support that's in
exim now, and it may be able to do SSL directly on the ssmtp port, without
the unneeded STARTTLS stuff.

Anyway, here's how it looks on my system
