Network and Communications Services (NCS) will be upgrading LISTSERV from version 14.4 to 14.5 on Friday, August 18. This newer version will provide list subscribers with new security features that will protect the contents of their email during transit. During this upgrade, LISTSERV availability will be intermittent between 10h00 and 17h00. Email posted to lists during this period will be temporarily held and distributed upon completion of the upgrade. NCS apologizes for any inconvenience this may cause.
