The value has to be a net-list, as described in section 7.15 (not a host-list),
and search expressions are not supported. Rationale: what is to be looked up? -
an IP address could be part of arbitrarily many potential network specifications.
[Only 33 (IPv4) or 129 (IPv6), I suppose, if the constraint on consecutive bits
in the netmask is to be enforced.] From Exim 1.70 onwards, an item in a host-list
can be the absolute path name of a file containing a list of address/mask pairs,
which is like "lsearch" in a way, but there is no alternative search method, and
the search type should not be specified.
