SMTP (Simple Mail Transfer Protocol)

SMTP, or Simple Mail Transfer Protocol, is the standard internet protocol used for sending emails across networks. It works like a postal service for digital messages, enabling email clients to send outgoing mail to a server, which then routes these messages to their intended recipients' email servers. SMTP handles the communication between servers to ensure that an email reaches the correct destination.

Note that SMTP is used for sending emails, not receiving them. For receiving and retrieving emails from a server, other protocols like IMAP or POP3 are used, which allow users to access their emails from various devices.
