Yes, crufty data causes a lot of bounces, and data should be cleaned...
But Harald's point was that *EVEN* in data *so* crufty that fully 1/4 of
it bounced because the destination was defunct, he had:
25.00% defunct
0.1% duplicates (same person, different addresses)
0.01% wrong person
which is a pretty strong evidence of Harald's assertion:

One would expect that in "clean" data, these mappings would be even stronger.
