I guess there room for error here - the message_id is defined as a
C-Octet String - not explicitly hex or decimal unlike the Delivery
Receipt id field unfortunately.

The receipted_message_id is optional - unfortunately it isn't being
populated for me so I'm forced to use the short_message which is defined
in .. more detail. 

Time to follow these up with provider. Cheers,
