My guess based on:

    https://github.com/Exim/exim/wiki/BlockCracking


is that you want to use

    acl_non_smtp = ...


in which you can use "$authenticated_id" to compare the user login
running Exim to your static whitelist. Someone better versed in
writing Exim ACLs should be able to help with that if you run into
trouble.
