|You can quite safely set your list to release at Midnight. Usually LISTSERV takes not more than about 5 minutes to send out digests and then will do the list mail in proper turn. And just to be pedantic, just because LISTSERV(R) sends it out does NOT mean it is delivered to the intended recipient soon thereafter, though hopefully that does occur. It is my understanding that most MTA clients will retry at most twice per hour if the MTA server is unavailable. or put a different way, *I* would not want to bet my life or business on the timely delivery of email. /Pete
