1. A system for communicating reply data width a communication unit comprising:
- a communication server, in communication with the communication unit, comprising a data transfer manager operable for receiving an optimized reply comprising a first data unit identifier and further data, forming a replica reply from the further data and a first data unit corresponding to the first data unit identifier, and forwarding the replica reply;
a host server, in communication with the communication server, comprising a store for storing the first data unit and being operable for, in response to a request for the first data unit by the communication server, forwarding the first data unit to the communication server, wherein the store comprises a mailbox of a user associated with the communication unit, the first data unit is a first email sent to the communication unit and having an associated first data identifier, the reply data is a reply email of the communication unit, the further data comprises a delta between the first email and the reply email, and the replica reply is a replica of the reply email.

Abstract
For optimized reply, when sending a reply (902) in a first embodiment a remote communication unit'"'"'s controller (206) generates a delta between a preceding message and the reply message, and forms an optimized reply (904) using the delta and an identifier of the preceding message. On receiving the optimized reply, the communication server uses the data unit identifier to retrieve (910) the preceding message from a further server (e.g., the post office mailbox of the user associated with the remote unit), reconstructs (914) the full reply from the retrieved message and the delta, and forwards (916) the full reply to the addressee. When receiving a reply for the remote unit (918), an index is preferably maintained by both units of mail stored at the remote unit. From this index a preceding message forming part of the reply is identified (920). An optimized reply is then similarly formed (922) and sent to the remote unit.
