[Exim] ROUTER_LOOKUPHOST

Hm,

I can't find any reference to lookuphost router in the docs, however
there's an options to enable lookuphost router.

root@poff:/usr/local/src/exim-3.951# grep ROUTER_LOOKUPHOST src/EDITME
ROUTER_LOOKUPHOST=yes

Am I missing something?

P.S. That's Exim 4 I'm talking about.
