It is possible that the postmaster is NOT the LISTSERV-maintainer. You could address e-mail to: [log in to unmask] I guess we (all) have learned a valuable lesson in changing * OWNER=. Always leave an escape hatch: insert a QUIET: on the "old" owner line, insert a "new" OWNER before e.g., old: * OWNER= pmw1@psuvm new (in the order shown): * OWNER= [log in to unmask] * OWNER= quiet:,pmw1@psuvm Later, once [log in to unmask] has been "confirmed" i.e., demonstrated to be a working owner account, have that account delete the QUIET: account [log in to unmask]
