Simple Mail Transfer Protocol (SMTP)
Simple Mail Transfer Protocol (SMTP) is the Internet standard for sending electronic mail between servers and from clients to mail servers. It defines commands and response codes for message transmission, routing via MX records, and relaying policies. SMTP's simplicity enables interoperability but requires additional mechanisms for security and deliverability.
