Whether the client must receive messages in the order of publication.
<p>By default messages sent to the {@code "clientOutboundChannel"} may
not be processed in the same order because the channel is backed by a
ThreadPoolExecutor that in turn does not guarantee processing in order.
<p>When this flag is set to {@code true} messages within the same session
will be sent to the {@code "clientOutboundChannel"} one at a time in
order to preserve the order of publication. Enable this only if needed
since there is some performance overhead to keep messages in order.
