Are you saying you are using ctime for the INTERNALDATE (or as its
fallback)?  I would think mtime would be better for that, since it
shouldn't change with a folder move or other non-data-altering
manipulations.  And that would leave ctime free for the fallback for the
expiry clock:  since it *does* change with a folder move, flag change,
etc, it would match what people would expect.  Unless I'm wrong :)

No opinions on non-maildir, you'd have to make something up.
