I've read through the "NEWS" file that came with 2.0.1 and there is no
mention of the admin bounce problem or a fix for it. I've also read
through the code to see if I can work out if a fix was inserted but I
didn't see anything obvious.
I did an experiment with my 2.0.1 system and mailman seemed to absorb a
bounce message generated by an approval request sent to a bogus list owner
and a line got reported in the bounce log so I assume that the bounce
machinery is being used for this somehow.
However, my bounce loop started with a bounce report from an Exchange
server and I have not been able to test that my newer 2.0.1 server will do
the right thing.
Can anybody reassure me?
