Ok, but I don't know the Pid of the process. For example I have a process
running in a node  and another process running in a node
, from node e1 I need send a message to application running in e2
node, in node e1 I write the next code
{application, } ! {self(),  "Message to send"},
receive
    {ok, Reply} ->
          .....
end

But if the application it's not running in the e2 node I don't receive any
error.
