This looks like Ubuntu 14.10. After installing from ISO disk image
in VirtualBox and catching up on all the updates since October 2014,
this is what I see:
$ uname -a
Linux ubuntu1410 3.16.0-30-generic #40-Ubuntu SMP Mon Jan 12 22:06:37 UTC 2015

On this system, Postfix 2.11.1 logging shows that the bounce service
works as expected:

In conclusion, whatever the problem is, it is not in Postfix. My
test shows that it works fine in a non-container environment on what
should basically be the same kernel as what you use.
Popular hype says that containers are just like the real thing, but
they are in fact a complex combination of resource management tweaks
to achieve isolation. All this may very well trigger bugs that don't
trigger in a non-container environment. I suspect a kernel race
condition. That is not something that I can or will program around
in Postfix.
