I googled and found:
CHANGE listname|* newaddr
This form of the CHANGE command can be used by any subscriber. It
must be sent from the currently-subscribed address and results in an
OK confirmation request being sent back to that address. This cookie
then MUST be confirmed by the currently-subscribed address, exactly
as it was entered, or the command will fail. This is the only case
where a LISTSERV cookie must be confirmed by a specific address. Note
that this assumes that the user still has login access to both
addresses, or at least the ability to send mail from the old address.

Change listname above to Paleofood, or use * wildcard to change name
on all your lists. And send comamnds to: [log in to unmask]
