There's really only one postfix queue.  You may be able to use the
qshape tool to sort the messages by next-hop.

A better solution is to use multiple postfix instances so you really
have two separate queues.  This is a little extra work to set up,
but the benefit is you can easily see when and where a bottleneck
occurs.
