[Exim] Auth SMTP Relay

I'm pulling my hair out trying to figure out the following. Can anyone tell me
what I'm missing besides a brain and a clue?

The configuration should allow relaying when authenticated.

I can authenticate on the local domain.

I don't get the option of authenticating outside the local domain. Ugh.

In the main section of config:
host_accept_relay = 127.0.0.1 : ::::1
host_auth_accept_relay = *
trusted_users = mail
smtp_verify = true

# If you want Exim to support the "percent hack" for all your local domains,
# uncomment the following line. This is the feature by which mail addressed
# to x%y@z (where z is one of your local domains) is locally rerouted to
# x@y and sent on. Otherwise x%y is treated as an ordinary local part

# percent_hack_domains=*

Transport section of config:
remote_smtp:
driver = smtp

Authentication section of config:
plain:
driver = plaintext
public_name = PLAIN
server_condition = "${if
crypteq{$2}{${extract{1}{:}{${lookup{$1}lsearch{/etc
/exim/passwd}{$value}{*:*}}}}}{1}{0}}"
server_set_id = $1

login:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = "${if
crypteq{$2}{${extract{1}{:}{${lookup{$1}lsearch{/etc
/exim/passwd}{$value}{*:*}}}}}{1}{0}}"
server_set_id = $1


Here's my test using exim on my off local domain box trying to come in.
