Method of transferring messages between computer programs across a network

Provided are methods and systems for message transfer between nodes of a communication network which reduce the occurrence of repeated transfer failures associated with a particular message or messages within a batch. When a batch of messages sent from a sender node cannot be stored at a receiver node, the receiver node identifies which messages within the batch caused the rejection and communicates this information to the sender node. The sender node records the destinations of the identified messages in a 'destination black list', and then separates messages having these identified problematic destinations from the other messages. The batch of messages is then retransmitted to the receiver, but with the messages which have the identified problematic destinations excluded from the batch. These excluded messages are then dealt with separately without causing repeated rejection of the batch.
