In practice, if this query is done on a periodic interval (e.g. daily), the date.saved will be roughly correct, and is usable as an age test for expungement.

Is there a way to force this value to be cached when the client actually saves or moves a message?

Done for save: http://hg.dovecot.org/dovecot-2.1/rev/c598f76eeeed

Fixed copy: http://hg.dovecot.org/dovecot-2.1/rev/b13b8267999d

It still doesn't add it to cache if it's not already cached in both the source and destination mailbox, but usually it should be after initial doveadm run.

Thanks, Timo.
