So, for completeness: 1) first update the list definitions, then 2) do the QUIET SET Of course there are always second order effects e.g., a batch job system like you might find in MVS (OS/390) might not "want" to get an ack or repro since the auto- mail might be unexpected. Or for certain distribution options, it might "break" the receiver's successful processing of the inbox.
