There are quite a few board@ mails stored under /srv/board. These date from 201605 to 201705.
Some are duplicates of those under /srv/mail/board but there are some unique ones, and some are copies sent to whimsy-vm3 for which there are copies sent to whimsy-vm4. Do these need to be copied to the new host? How long do board emails need to be kept for use by Whimsy? S.
