Hi, that is probaby because Claws Mail only saves the opened folder's
message cache (including tags or message flags like new, unread, etc.)
to disk on program exit, or when you switch to another folder.
The "Metadata handling" setting has no effect here. This preference was
added during the Great Fsync Scare of 2009, and is about what
happens when the cache actually *is* being written.
What we could do is write the cache much more often, such as every time
user marks a message as read. Perhaps it could be controlled by a
checkbox in preferences, for those who want to limit their disk I/O,
and are certain that their system and Claws Mail are both stable, and
that their desktop environment shuts applications down cleanly on log
