I was thinking the same thing. Here is a very rough first cut, proof of
concept script. Watch out for wrapped lines. You may have to change
the #! python command. The script needs to be stored in the bin/
directory with the other command line scripts in order to find the
paths.py module it imports.

It will grow a --help option and at a minimum, an option to specify a
pattern and print only those names that match the pattern (although
with the primitive script below, you can always pipe it into grep).

The above is almost correct. In Mailman 2.1.5, you can turn off
everything but the VERP probes in mm_cfg.py. Then the above changes
will replace '+' with '=' except it should be

   VERP_PROBE_REGEXP = r'^(?P<bounces>[^=]+?)\=(?P<token>[^@]+)@.*$'

And yes, the probe token is always a hex confirmation string, not the
user=host address format.
