Messaging system apparatuses circuits and methods of operation thereof

A messaging system comprising a messaging server having a processor configured to:

• a) receive a message from a second mobile messaging client device executing a messaging application and associated with a second authorized user;
• b) store the message in a database;
• c) transmit to a first mobile messaging client device executing the messaging application and associated with a first authorized user, a notification of the presence of the message at the messaging server, where the message is addressed to the first authorized user;
• d) receive from the first mobile messaging client device a request to retrieve the message, the request including client authentication data;
• e) validate the first mobile messaging client device based on the client authentication data;
• f) transmit the message and a message attribute to the first mobile messaging client device, where the message and the message attribute are stored in non-volatile memory in the first mobile messaging client device at least until the message is managed by the first mobile messaging device in accordance with the message attribute;
• and
• g) receive from the first mobile messaging client device a message management notification generated by the first mobile messaging client device in connection with managing the message in accordance with the message attribute at the first mobile messaging client device.
