	Hi,
the backup skips caches, and as the evolution-ews account is only a
local copy of the remote data, thus everything is stored in the cache,
then those are skipped from the backup.

Interesting, I didn't know that. The Received column date is derived
from Received headers, or I always thought it is, but even for messages
which do have the Received header the Received column is populated with
the date which corresponds to the date when the message was added into
an On This Computer folder.

That feels like a bug in the Maildir provider [1]. For example MBOX
(spool) provider doesn't suffer of this and derives the Received time
from the message headers.

	Bye,
	Milan
