So, Mailman is delivering via the local Postfix and not directly to the
remote server.

Postfix was doing DNS lookups on the sending domain for all messages
which slowed it way down. You avoided this by the change you made.

You can move the .pck files back without stopping/starting Mailman.

If you move the .bak files without renaming them, they won't be
processed until you restart Mailman. If you rename them to .pck, they
will be processed along with the others without a restart.

BUT, the messages in the .bak files have been 'partially' processed and
possibly delivered to some recipients. You can examine the .bak files
with bin/dumpdb -p to see what they contain and decide if you want to
reprocess them.
