MQ Client connections and size limitations

We have a client connection to MQ that process messages under 4MB fine but if the message is larger, the message gets stuck in the Cloverleaf queue.   The MQ Series default is 4 MB but the server size indicates they are set up to receive up to 64 MB.

Is there a Cloverleaf setting or limitation that only allows the use of the MQ Series default size?   Is there someplace on our side that we can update the maxmsglen variable?
