Messaging system apparatuses circuits and methods of operation thereof

1. A method for managing a messaging system comprising the steps of:

a) receiving a message from a first mobile messaging client device executing a messaging application and associated with a first authorized user;

b) storing the message in a database;

c) transmitting to a second mobile messaging client device executing the messaging application and associated with a second authorized user, a notification of the presence of the message at the messaging service, where the message is addressed to the second authorized user;

d) receiving from the second mobile messaging client device a request to retrieve the message;

e) received a message attribute comprising an instruction to limit a functionality of the message;

f) applying the message attribute to the message bases on a message characteristic and updating any existing corresponding message attribute; and

g) transmitting the message and the message attribute to the second mobile messaging client device that managers the message in accordance with the message attribute, wherein managing the message comprises limiting the functionality of the message bases on the message attribute, and wherein the message attribute comprises a predetermined message viewing time after which the message content cannot be accessed at the second mobile messaging client device.

2. The method of claim 1 , wherein d) further comprises: receiving from the second mobile messaging client device a request to retrieve the message, the request comprising client authentication data.

3. The method of claim 2 , further comprising the step of, prior to g), validating the second mobile messaging client device based on the client authentication data.

4. The method of claim 1 , wherein the message characteristic comprises content of the message.

5. The method of claim 1 , wherein the message characteristic comprises a recipient of the message.

6. The method of claim 1 , further comprising the steps of:

h) receiving an updated message attribute comprising an instruction to limit a functionality of the message;

i) applying the updated message attribute to the message and updating any existing corresponding message attribute; and

j) transmitting at least the updated message attribute to the second mobile messaging client device.

7. The method of claim 1 , further comprising: h) receiving from the second mobile messaging client device an automatic notification that the second mobile messaging client device has managed the message in accordance with the message attribute.

8. The method of claim 1 , wherein step a) further comprises: receiving a message and a message attribute from a first mobile messaging client device executing a messaging application and associated with a first authorized user.

9. The method of claim 1 , further comprising: h) transmitting to the second mobile messaging client device additional message attributes for the message.

10. The method of claim 1 , wherein the message attribute comprises a predetermined message deletion time.

11. The method of claim 10 , wherein the predetermined message deletion time is based on a time the first mobile messaging client device sends the message.

12. The method of claim 1 , wherein the message attribute is a number of times the message may be accessed at the second mobile messaging client device.

13. The method of claim 1 , wherein the message attribute designates a geographic location of the second mobile messaging client device in which the message may be accessed.

14. The method of claim 1 , wherein the message attribute comprises one or more of an ability to print, save, and forward the message.

15. The method of claim 1 , wherein the message content includes at least one of text and an attachment.

16. The method of claim 1 , further comprising: h) managing the message in accordance with the message attribute.

17. The method of claim 1 , wherein the first authorized user defines the message attribute of the message.

18. The method of claim 1 or 17 , further comprising: editing the message attribute of the message.

19. The method of claim 1 or 18 , further comprising: adding one or more additional message attributes to the message.

20. The method of claim 1 , wherein the message attribute is defined by a user having an administrator privilege.

21. The method of claim 1 or 20 , wherein the message has an identified recipient group and the attribute of the message is based on the identified recipient group of the message.

22. The method of claim 1 or 20 , wherein the message has an identified recipient position and the attribute of the message is based on the identified recipient position of the message.
