NANOG Mailman upgrade - Saturday, April 18th

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.
