Thanks, the pointers helped me figure it out. Below is my setup for
anyone that might be looking for similar.

In /etc/exim/allowed_to_relay:
2.3.4.0/29: 2000 / 24h
6.7.8.0/24: 10000 / 24h

In /etc/exim/exim.conf:

 acl_check_rcpt:
   ...
   defer ratelimit = ${lookup {$sender_host_address} iplsearch
{/etc/exim/allowed_to_relay} {$value} }
           message = Sender rate exceeds $sender_rate_limit messages
per $sender_rate_period
