For a while there, I had several weeks of "no unhandled bounces". Now I'm getting a lot that aren't being caught, and I'm going to go start diagnosing them.

Barry, or anyone, do you have anything other than the code itself to help understand the various sorts of bounces that are caught by the various Bouncer modules? (i.e. samples or other explanatory docs?) I expect the answer to be "no", but it doesn't hurt to ask.
