One of the MIT LISTSERV maintainers tells me that my list ([log in to unmask]) is sending mail separately to each subscriber, rather than using the distribute mechanism and batching messages to users at a single host. The list header contains the "Mail-Via= DIST2" setting. Do you have any idea why messages might be sent separately to each subscriber? /David M. Rosenberg [log in to unmask] 1-617-253-8054
