I did not find a solution for this by glancing through the docs.
Granted that nobody else commented on this mailing list, I'd like to
suggest that you ask on the upstream mailing list exim-users at exim.org.

If people there tell you to go here, tell them that Debian doesn't
modify exim's authentication behavior. I'll monitor exim-users and
intervene if necessary.

Sorry to give you the runaround. I apologize.
