[exim] RATELIMIT

I want to ratelimit all user not authenticated.

warn ratelimit = 100 / 2h / per_rcpt / strict
         delay     = ${eval: ${sg{$sender_rate}{[.].*}{}} -
$sender_rate_limit }s

I imagine I add something like this?

!authenticated = *


Then I want a separate ratelimit for those that are authenticated.
Can someone tell me how to do that?
