SMTP stands for Simple Mail Transfer Protocol. It’s a standard protocol used for sending and receiving emails over the Internet. SMTP is responsible for the transmission of emails from the sender’s email client or server to the recipient’s email server. It’s a fundamental component of the email communication process.

Here’s how SMTP works:

Client-Server Communication: When you send an email, your email client (such as Outlook or Gmail) uses SMTP to connect to your email server. This server is responsible for sending your email to the recipient’s server.

Addressing and Routing: The email client provides the sender’s and recipient’s email addresses. The sender’s server uses DNS (Domain Name System) to determine the recipient’s server’s address.

Authentication: Many SMTP servers require authentication to ensure that only authorized users can send emails through the server. This helps prevent unauthorized use.

Message Transfer: Once the recipient’s server is identified, the sender’s server establishes a connection to it. It then transfers the email message along with the necessary metadata, such as the sender’s address, recipient’s address, subject, and body.

Queueing and Forwarding: If the recipient’s server is temporarily unavailable, the sender’s server will often queue the email for later delivery. The recipient’s server, upon becoming available, retrieves the queued email and delivers it to the intended recipient.

Delivery Confirmation: After successful transmission, the sender’s server receives a confirmation from the recipient’s server that the email was delivered or successfully queued.

SMTP is primarily concerned with the sending of emails and doesn’t handle tasks like receiving emails, storing them, or organizing them into folders. That’s the role of other protocols like POP3 (Post Office Protocol 3) or IMAP (Internet Message Access Protocol).
