So exim looks up the connecting host and compares strings rather than
looking up the name in the config and compare IPs? Or do a forward
lookup of the IP gathered from the reverse lookup to make sure they
match (I'd say that's pretty much required for any DNS based
'authentication', but what do I know?).
