[exim] blocking on failure of reverse_host_lookup

Hi all,

I though I'd seen people post on the list about blocking outright on
reverse_host_lookup - however having implemented this yesterday, it
seems like it quite possibly did block the occasional email. Before
yesterday, it was just used as part of a scoring system.

What are peoples thoughts on this?
