Have you checked the "authenticated" condition before the "ratelimit"
condition? If not, $authenticated_id won't be set, and the limit will
apply to the whole MTA regardless of the client.

This is very strange. Why are your client connections apparently coming
from localhost? That would explain why removing the $authenticated_id
lookup key (leaving the default $sender_host_address) doesn't change
anything, because the client IP address has been rewritten before Exim
gets to see it.
