Was thinking about trying it out. The query is a little weird. is there
and easy way to query this from Exim?

How To Query EmailReg.org
The query should always go to the DNS Zone of "*/resl.emailreg.org/*" in
the following format:
(from domain).(ip).resl.emailreg.org
For example. If you receive an email from IP address 1.2.3.4 with a from
address of fred@???, you would do a query of
"example.com.4.3.2.1.resl.emailreg.org" to learn if the IP address and
domain are registered.
The return codes are structured to provide as much information as
possible about the IP address and domain. The return codes are
structured similarly to most RBL like services: 127.0.x.y Where X is a
EmailTypes and Y is the registration status.
