Whew.. Thanks for making this clear. The documentation is very unclear
about this. I reread it several times, but I had been thinking it applies
to a host that is compared against a host list (or at least to a single item
in a host list). I was unsure until I read your explaination.

In example:

===================================
If any item that follows +ignore_unknown requires information that cannot
be found, Exim ignores that item and proceeds to the rest of the list.
For example:

accept hosts = +ignore_unknown : friend.example : \
               192.168.4.5


accepts from any host whose name is friend.example and from 192.168.4.5,
whether or not its host name can be found. Without +ignore_unknown,
if no name can be found for 192.168.4.5, it is rejected.
====================================

According to this, "Without +ignore_unknown, if no name can be found
for 192.168.4.5, it is rejected". But according to what you say (and
what I see in preactice), "without +ignore_unknown, if no name can be
found for 192.168.4.5, whole list is discarded and any host does
not match the list".
