First of all, you are confusing DEFAULT_MAX_MESSAGE_SIZE with a list's
max_message_size. DEFAULT_MAX_MESSAGE_SIZE is a Defaults.py/mm_cfg.py
setting that is used to set max_message_size for a list when the list is
created. The list's max_message_size is apparently what you want to change.

The next thing you are missing is that settings not mentioned in the
input file to bin/config_list are unchanged, so all you need is a one
line input file

max_message_size = ...

and run config_list over all lists with that input.  There are other
ways to do this using bin/withlist too.

In your case, you could do something like

#!/bin/bash
cd /path/to/mailman
input=`mktemp`
echo "max_message_size = ..." > $input
for list in `bin/list_lists -- bare`; do
   bin/config_list -i $input $list
done
rm $input
