This is True. SMTP (Simple Mail Transfer Protocol) operates on port 25 and is the standard protocol for email transmission. An SMTP server accepts outgoing mail from email clients (using authenticated SMTP on ports 587 or 465), validates the sender and recipient addresses, and relays messages to other SMTP servers for delivery. It handles both client-to-server submission and server-to-server relay, making it responsible for routing email across the internet until it reaches the recipient's mail server.
