commit 767a318eea666a3af4881e3f351dcdabdf2df216
Author: Oswald Buddenhagen <o...@users.sf.net>
Date: Sat Jun 18 12:52:35 2022 +0200
add new sync operation 'Old'
this is essentially the same as 'New', but for previously seen messages,
such as those that would have been instantly expunged (because they were
marked as deleted), those that we failed to store for some reason, and
already expired ones that are now flagged.
