Abstract
A method and apparatus for reliably delivering messages (200) from a central terminal (102) to a communication receiver (130) in a communication system (100), such as an electronic mail system. The central terminal (102) sequentially transmits messages (200) to the communication receiver (130) and the communication receiver (130) receives transmitted messages (200) over a first communication medium (122). The communication receiver (130) reconciles messages that it failed to receive over the first communication medium (122) with the central terminal (102) over a second communication medium (152). The reconciliation between the communication receiver (130) and the central terminal (102) utilizes message sequence identifiers (208) transmitted with the messages (200) that identify the transmission sequence of the sequentially transmitted messages (200).
