About this document

Understanding SMTP and Email Transmission by Sri Das is a document available to read on EtoBox.

SMTP is the standard protocol for transferring email between servers over TCP/IP. It uses TCP port 25 and defines email as a text file with an envelope containing sender/receiver addresses and a message with a header and body. SMTP uses a client-server model where clients like email programs connect to SMTP servers to transmit messages. The communication involves commands, responses, and status codes to transfer messages through multiple servers until it reaches the destination mailbox.
