You've been using Exim for so long now that you should be able to do
this in your sleep.

dnslists = x/hostname

Where "hostname" is the acl variable representing the appropriate domain
name to look up, and "x" is constructed from the connecting ip with its
octets reversed using one of the relevant expansions, appended with a
full stop and the lookup domain.

If you want the complete config snippet, I'm happy to sell you it.
