On a relay server, I think it would be a lot easier to do recipient
callouts in RCPT acl than having to haul a flatfile everytime you make
changes to the domain.

# This statement accepts the incoming recipient address if the domain is
# one of domains for which this host is a relay, but again, only if the address
# can be verified.

accept  domains     = +relay_to_domains
        endpass
        message     = Unrouteable address.
#       verify      = recipient
        verify      = recipient/defer_ok/callout=10s/callout_defer_ok



If that is not satisfactory, then you will have to craft a router (and a
transport to boot) with a suitable condition. Something like below comes
to mind, but untested!!

condition = ${lookup{$local_part}lsearch{/usr/local/etc/exim/$domain}{yes}{no}}
