Answer:

In SMTP (Simple Mail Transfer Protocol), the entity that is used to transfer the message is called the "Mail Transfer Agent" (MTA). The MTA is responsible for relaying email messages from the sender's mail server to the recipient's mail server. It follows the SMTP protocol to establish a connection, transfer the email data, and handle any necessary routing and delivery tasks. The MTA acts as an intermediary between mail servers, ensuring that the email message reaches its intended destination.
