The next main update will resolve an issue with in-game mails in the bank/postal service interface that weren't deleted after the indicated timer had run out. After the next main update these messages will be deleted correctly according to the countdown timer.

We understand that many players have used in-game mails to store unused items. However, the system was not designed to store items past 30 days and provide unlimited storage space. This is why we must resolve this bug. So please make sure you pick up all pending in-game messages on time.
