host_accept_reply? Do you mean relay_from_hosts, pehaps? And also,
there is not such a thing as the address of a domain. You could
compile the list of addresses that correspond to hosts in a certain
domain, and this would be part of a zone transfer (in dns parlance).
But (and a big one): this list of addresses does not necessarily
correspond to the list of addresses whose *reverse* dns is in your
domain. Anyone can get an ip address they do dns for, and place the
reverse of it into your domain.

MX has nothing to do with this, unless you want to do relay from
based on MX, which is a very BAD thing to do (and I bet some open
relay tester would get you there).
If you want to accept from a host within a domain (in the sense that
both their ip address resolves to a hostname in that domain *and*
that hostname in turn resolves in the original ip), then you should
be able to use:
accept hosts = *.xxxxxx.com
since hosts lookups in exim perform both the reverse and the forward lookup.
