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]
