No, I was only interested in whether they produced appropriate output as
opposed to an exception and traceback. You might look at web_page_url
for web server issues (see below), but that shouldn't affect postfix.

Yes. This is consistent with Postfix not finding the old lists.

Look at /etc/init.d/mailman. Is it running the same mailmanctl as you
are running by hand.

Look in every aliases file referenced by Postfix in alias_maps. There
should at least be /etc/aliases and /var/lib/mailman/data/aliases and
maybe others. Are there duplicate aliases for any mailman lists. Do they
all point to the same wrapper (/usr/lib/mailman/mail/mailman).

When you said the web server doesn't recognize the old lists, did you
mean just they don't appear on http://example.com/mailman/listinfo or
that also you get a 'no such list' from

Continuing to grasp at straws, try

sudo find / -name config.pck

Does that return more than just the one
/var/lib/mailman/lists/LISTNAME/config.pck for the new lists.

If you are running SELinux, try disabling it.
