... So point the sender to a special, single, up-to-eight-bytes-long,
"error absorber" address - one for every SERVER, not LIST - and let
LISTSERV process them at its spare time, applying some heuristics
as for what the original LIST name was, to tell the owner, or else -
hand it over to Postmaster.
 
... Or point the sender to a special error box that *should* be defined
for each list (possible today as an option, I know, but make LISTSERV
handle this box automatically and forward rejections to appropriate
people..).
