Nope. While it's not a problem on the systems I'm adminning now, a year ago quite a large chunk of the internet could not seem to properly reach our DNS to resolve reverse IP lookups on our IP blocks. We had the records in place, *some* systems could resolve our reverse lookups, but quite a few didn't seem to be able to. I would guess that while this isn't likely on larger providers, smaller providers *do* get caught in the middle of someone else's DNS problems/delays. -kgd -- "Sendmail administration is not black magic.
