It's not clear why you would want to create a new channel per message.
 Typically one gets a connection, then multiplexes it into separate
channels and uses each channel for some conceptually related chunk of
behavior, e.g. publishing notifications of some sort, consuming messages,

If you want such an assurance you'll either have to perform that publish
with the context of an AMQP transaction (synchronous and kind of expensive)
or use publisher confirms, in which case you register an asynchronous
listener for confirm receipts that the broker sends when it's done what you
asked for, to the standard you asked.
