SMTP is a text-based protocol that allows client-server applications to send and receive email messages by specifying the message sender, recipient(s), and the content to be sent. Email messages are sent through SMTP servers using a store-and-forward model, where the message is sent from client to server and is temporarily stored on the server until it is sent to the destination server. SMTP uses Port 25 as its default communication port.
