I'd try this:

       hosts        != lsearch;/etc/exim/whitelist-hosts

It's completely untested and I'm just getting that from reading the
docs (chapter 9, section 9.1 and 9.3). Note that if you want to use
wildcards, you'll likely want to try it with nwildlsearch instead of
just lsearch. Read section 9.3 for more detail of the differences.

You just want the single lookup type, so your whitelist file can be
just a single line with a hostname, a hostname with a colon, or a
hostname with a colon and some value (comments) afterwards. Since
you're only looking up the single value, you'll only be looking at the
value before the colon.

If any of this is wrong, I apologize. I don't really use any of this
file based stuff because just about everything I do is stored in a
database. But hopefully it gets you started in the right direction.
