I'm not sure how I got over this and got usable "date.saved" cache values, and why it stopped working. Maybe I need to set something like
mail_always_cache_fields = date.saved mail_cache_fields = date.saved
to force date.saved to be cached.
This doesn't work -- it's not a cachable value.
To get around the wonky date.saved values, I used date.received instead, which seems to have more reliable values
doveadm -f tab fetch -u {user} "uid date.received" mailbox {box}
and the corresponding expunge command would be
doveadm expunge -u {user} mailbox {box} BEFORE {time-limit}
It not quite the same as it's not the time it was copied into {box} but rather, the internal date, which may be earlier (i.e when it was received).
