I've checked LISTSERV options, and they're what they ought to be; I've gotten <1% of messages in the last month.
I'm sending problem report to marist's postmaster, listmaster, etc. But I'll admit I am far, far, far from confident that they'll ever respond. In many years, I haven't yet had a listserv-related question or problem which has gotten as much as an acknowledgement without serious repeated effor and, sometimes, phone sleuthing. - Allen S. Rout
