[Mailman-Developers] Many more bounces lately

[Dan Mick]

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.
