a sorter for unloading each of the holders based upon the data associated with each of the holders, so that the mail pieces and the exceptional mail piece are sorted according to said desired sequence.

2. The sorting system of claim 1, wherein the exceptional mail piece is a mail piece having a shape that is suboptimal for automatic singulation.

3. The sorting system of claim 2, further comprising means for separating the exceptional mail piece from the sorted ones or the group of mail pieces, the means for separating being distinct from the singulator.

4. The sorting system of claim 3, wherein the means for separating is configured to separate the exceptional mail piece based upon determining at least one physical characteristic of the mail piece.

5. The sorting system of claim 1, wherein the data comprises information about a destination address for each of the mail pieces.

6. The sorting system of claim 1, wherein the desired sequence is a mail carrier route sequence.

7. The sorting system of claim 1, wherein the means for associating is a computer device having a database capability.

8. The sorting system of claim 1, wherein the second loading station is located upstream from the first loading station.

9. The sorting system of claim 1, wherein each holder is dimensioned for receipt and holding of the mail piece from the group of mail pieces and the exceptional mail piece in a vertically aligned face to face relationship.

10. The sorting system of claim 9, wherein the holders are formed by adjacent bin dividers along a mail path.

11. The sorting system of claim 10, wherein the second loading station is a manual loading station and is located along an endless loop upstream from the first loading station.

12. The sorting system of claim 11, wherein the first loading means and the second loading means are a device for opening the holders so as to receive the mail pieces and exceptional mail piece, respectively, and the holders automatically subsequently close as they move along their path.

13. A method for sorting a group of mail pieces and at least one exceptional mail piece into a desired sequence, comprising:

arranging a plurality of holders, each dimensioned for receipt and holding of a mail piece from the group of mail pieces and the exceptional mail piece, the holders being for moving downstream;

singulating the group of mail pieces at a first loading station;

receiving the exceptional mail piece at a second loading station;

collecting data about the exceptional mail piece;

manually loading the exceptional mail piece from the second loading station into a first one of the holders so as to occupy said first one of the holders;

associating the data about the exceptional mail piece with said first one of the holders;

automatically loading each mail piece in the group of mail pieces from the first loading station into an unoccupied one of the holders which were moved downstream from the second loading station;

collecting data about each mail piece in the group of mail pieces; and

associating the data about each mail piece in the group of mail pieces with said unoccupied one of the holders into which said each mail piece was loaded;

determining which holders have been loaded with the exceptional mail piece and advancing the holders so that an empty holder for the each mail piece being automatically fed can be loaded into the unoccupied one of the holders; and

unloading each of the holders based upon the data associated with each of the holders, so that the mail pieces and the exceptional mail piece are sorted according to said desired sequence,

wherein the exceptional mail piece is a mail piece having a shape that is suboptimal for automatic singulation, and further comprising a step, prior to the singulating step, of separating the exceptional mail piece from the sorted ones or the group of mail pieces, in order to bypass a singulator that performs the singulating step.

14. The method of claim 13, wherein the data comprises information about a destination address for each of the mail pieces.

15. The method of claim 13, wherein the desired sequence is a mail carrier route sequence.

16. The method of claim 13, wherein the separating is based upon determining at least one physical characteristic of the mail piece.

17. The method of claim 13, wherein the second loading station is located upstream from the first loading station.

18. The method of claim 13, wherein the collecting data about the exceptional mail piece is prior to the manually loading.

19. The method of claim 18, wherein the manually loading is performed upstream of the automatic loading such that the first one of the holders will pass by an automated loading station for the automatic loading.

20. The method of claim 19, wherein filled holders arriving downstream at the automated loading station will advance past the automated loading station so that a next empty holder for the mail piece is feed by the automated loading station.

21. The method of claim 20, wherein the manually loading and the automatically loading has shared time in a sequencing cycle.

22. A sorting system for sorting a plurality of exceptional mail pieces into a desired sequence, comprising:

a plurality of holders, each holder dimensioned for receipt and holding each of the plurality of exceptional mail pieces, the holders moving downstream in the sorting system;

a loading station, where the plurality of exceptional mail pieces are received into the sorting system;
