We do that by setting Daily-Threshold=1 and keeping the list held all the time. Then we use cron jobs to free the list when we want to allow a message to be sent and, a short time later, hold the list again. If one or more messages is queued, one of them will be sent each time the list is freed. Note that because of the way LISTSERV queueing works, you can't be certain which one will be sent each time.
