The NANOG Mailman version will be upgraded on Saturday, April 18th at 7:00AM EDT. The new version supports wrapping emails which have strict DMARC enforcement set in order to prevent the emails from bouncing and causing members to be unsubscribed. We anticipate the upgrade to take no more than 15 minutes, during which time the NANOG mail server will not accept new messages. Any messages sent at this time should be queued and delivered after the server upgrade. Regards, Larry Blunk NANOG Communications Committee
