Simple Mail Transfer Protocol (SMTP) Explained: Everything You Need to Know

SMTP, which stands for Simple Mail Transfer Protocol, serves as the foundational protocol governing the transmission of emails across networks, most notably the internet. It functions as an application layer protocol within the TCP/IP suite, defining the rules and mechanisms for sending, relaying, and receiving emails between mail servers and email clients.

At its core, SMTP enables the reliable delivery of electronic messages by facilitating the interaction between mail servers. When an email is sent from one user to another, the sending email client communicates with an SMTP server to initiate the delivery process.

SMTP operates using a text-based command-response model, where a series of commands and responses are exchanged between the client and the server. This communication establishes a connection, authenticates the sender, and transfers the email content to the recipient's mail server.
