I ought to also point out that using config.db or config.pck will only
get you information about _current_ subscribers, including those whose
subscriptions are still present but disabled because of bounces.
Pulling a pure and simple list of email addresses from the latter group
out of the config database generally requires a bit of jiggery-pokery
with a text editor, but the database dump has everything fairly clearly
labeled.  You can use the ~mailman/bin/dumpdb utility to get a
plain-text dump of the database once you determine the full path to the
config database (config.db or config.pck).  If you can get a backup copy
of the config file from before about Apr. 8 then all the information you
want will be there.  Absent this, once actual auto-unsubscriptions
started, the only way to recover auto-unsubscribed addresses is by
pulling them from Mailman's subscribe log file, as noted in my previous
