Typically sends are async if any of these are true

* async sending is explicitly enabled on the connection/connection factory
* you are using non-persistent messaging
* you are inside a transaction (the commit/rollbacks are sync).

The sync v async never changes based on the type of the destination
(or whether a destination is specified on a send versus using the
default etc)
