Then you won't be able to fix this. You'll need to get whoever does
have access to do it.

This is Mailman 2.1.4 or older and the file lists/LISTNAME/request.db

but before doing so it is always a good idea to examine the files in
qfiles/shunt with bin/dumpdb or bin/show_qfiles and cull out any old
