You exim client does not even try to authenticate, although advertised.
I have no clue of exim, but browsing through the documentation it looks
like you need to adjust the options host_require_auth and/or
host_try_auth

http://www.exim.org/exim-html-4.50/doc/html/spec_33.html#SECT33.5

that probably only lists the IPv4 address at the moment.
