An electronic mail (email) communication system includes a mobile office platform. A direct access proxy accesses an electronic mailbox of the user and pushes email from the electronic mailbox of the user to a wireless communications device. A web client engine is operative with the mobile office platform and includes a port agent module that communicates with the wireless communications device over a port agent connection. It is operative to receive a message from a wireless communications device as a request corresponding to a job to be completed. A worker module receives the message from the port agent module and completes the job. The web client engine attempts to process jobs within a specified delay time, and if successful, transmits an acknowledgment (ACK) to indicate the job has been completed without saving the message to a jobstore database. If the job has not been completed within a specified delay time, the message can be saved to the database.
