It works great for me.

My exim install doesn't offer AUTH PLAIN until STARTTLS
has kicked in.

This may be because I also have the near the
beginning of my config:

auth_advertise_hosts = ${if eq{$tls_cipher}{}{}{*}}

... which the original poster also has.

(In my original post, I described only my auth
acl)

So, do you still disrecommend this config, which
doesn't offer AUTH until TLS is started? If yes,
can you tell me why?
