Are the timestamps wrong in the database? They should contain the
timestamp of the oldest save-date of message in the mailbox.

Also check that the save-dates are as expected in the mailbox itself:

doveadm fetch -u user at domain date.saved mailbox Trash 1

And finally, I added some more helpful error and debug logging (which
you'll get with doveadm -D):
