A sorting system for mail items includes sorting registers, a storage module operating on a last-in/first-out principle, a sorting circuit to convey a stream of mail items. The sorting registers and the storage module are connected via switch points to the sorting circuit, wherein the storage module comprises a storage area and an insertion function. An extraction function extracts mail items from the storage area, and a process controller controls the mail item stream and the switch points. The process controller sets, if there is a conveyance fault, part of the switch points so mail items intended for the faulty sorting registers are introduced into the storage area. When the fault is rectified and/or a predefined occupancy level is reached, mail items stored in the storage area are extracted by adjusting a remaining feeding of mail items into the mail item stream, and fed to the sorting registers. |
