A messaging system (1) has interfaces for receiving and for retrieving messages with content, and an interface for requesting message transcoding by an external platform (7). The system (1) dynamically selects if transcoding is required for a message and, if so, how to perform the transcoding. It determines if transcoding is required according to a determination of capabilities of the receiving device and the nature of the content. Advantageously, the system dynamically learns rules for making this determination, by automatically observing: messages sent from devices of the same type, and/or messages sent to the devices of the same type by trusted systems, and/or modifications performed by an external transcoder on an original message and the resulting transcoder output. A probing component automatically parses received messages to determine content type of a received message to determine the nature of the content. |
