The "originator" of a message is the agent responsible for originating it.
In layman's terms, the originator is the composer of the message.
The "sender" of a message is the agent responsible for submitting it to the
network. In layman's terms, the sender is an agent, human or otherwise,
that handles the dirty work of handing the message off to the mail transfer
The MTA is the agent responsible for transmission and delivery.
Here is a mundane example that should make it clear: I need to send a CD-R
with a software update to one of our satellite offices. I pack it up and
put an address on it. I am the originator, the agent responsible for
originating the package.
I give it to Elaine, our corporate secretary. She checks the address, then
calls the FedEx guy to pick it up. When he arrives, she gives him the
package and is done with it. She is the sender, the agent responsible for
handing the package to the transfer agent. I do not think that anyone can
rightly say that Elaine is the originator of that package, especially when
my name is in the return address area.
FedEx is the transfer agent, the agent responsible for getting it from here
to there. The package will pass through several FedEx checkpoints, each
adding its stamp to the log that follows the package, just as a relay host
adds a Received header to each piece of mail it processes.
Arpanet/Internet mail follows the exact same paradigm.
