[Exim] (dirlist) lookups

..come on, Philip, I need some help... ;)

I have
..
host_accept_relay = lsearch;/somefile
..

will the return code of the lookup
result in a acceptance (or denial)
of the relaying host?

The point for me is... on my new lookup:
Do I need to match by myself or is it
possible to just return an item list
(like the ordinary host_accept_relay
= /somefile) and let exim make the
decision?

So I could just return a list of IPs e.g.?
