I noticed that sometimes `aerc` is sorting items in an order I would not expect it to. I expect sort to be always from newest to oldest which I think is the default in `aerc`. It happens in folders other than inbox. To me it seems it's sorted by the addition to given folder, not the email's received/sent timestamp. I am using mailbox format for storing emails. My email provider is Fastmail. The configuration file for mbsync/isync contains `CopyArrivalDate yes` option which should avoid these problems. Is it possible this is problem with `aerc` or do you think it's related to how I store emails? Thanks.
