SMTP is a mail transport protocol, and in mail every single packet is important. Learn how the two transport protocols differ, when to use each, and how QUIC and WebRTC build on top of them. SMTP is a connection-oriented, text-based protocol in which a mail sender communicates with a mail receiver by issuing command strings and supplying В тексте рассмотрим два самых популярных протокола транспортного уровня — TCP и UDP — и сравним их. SMTP relies on TCP to ensure emails are delivered reliably. Im Gegensatz zu TCP überprüft UDP nicht, ob die Daten erfolgreich Protocols like SMTP (Simple Mail Transfer Protocol) and IMAP (Internet Message Access Protocol) rely on TCP for sending and receiving emails. It uses TCP because it's very important that every word of an email is sent correctly and Although port 465 is the recommended port for secure SMTP email transmission, some systems sometimes rely on ports 25, 587, or 2525. Why does SMTP uses TCP and not UDP? Considering SMTP, it makes more sense to use TCP over UDP. In November Is SMTP based on UDP protocol?
