Sorry, I'll try to clarify my question.

I assumed that your "Yes" referred to my comment on TCP being used to 
ensure ordering when delivering messages over the network. TCP itself 
ensures reliable delivery as well as maintaining the order of messages. 
However, the documentation [1] specifies message delivery to be 
at-most-once, i.e., messages can be lost. Why is the ordering ensured by 
TCP, when the delivery is not? 


Ok. If that is the case, is the reason reliability is not guaranteed that

Hopefully, this clarified the question, i.e., even if the message is 
delivered to the network buffer it may still not be passed to an actor 
because the node may crash or mailboxes may be full.
