After asking the question, I decide to "test" the batch command. "QUIET DELETE listname DD=X //X DD * internet-address1 internet-address2 /*" I forgot to use the "TEST" argument. Well it worked. It appears that if these subscribers would have been subscribed to more than one list I owned they would have been deleted from all (global) lists. True or false? Is there a parameter to limit the bulk delete to simply the desired (local) list? Command results: ---------- Forwarded message ---------- > Quiet delete LISTNAME DD=X The following users have been removed from the LISTNAME list: [log in to unmask] [log in to unmask] [log in to unmask] [log in to unmask] No notification has been sent. Global deletion process complete, 4 entries removed.
