So you want a reverse lookup that doesn't match the forward lookup?

Where exactly are you getting slowed down by this reverse lookup, smtpd?

I'm going to disagree: the reverse lookup is a very firm convention.
127.0.0.1 reverse resolves to localhost. (note the trailing dot,
I think the jury is still out on that one ;-)

Nobody is meant to request recursive lookup for 127.0.0.1, although
many configurations do, of course.  They deserve what they get,
don't they?

Lastly, the idea was to get rid of the delay and failure in the
revcerse l.ookup, which I believe is not achieved by the suggested
/lib/ndb/local (why not /lib/ndb/common?) entry.
