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?
