I. What is SMTP and how it works?

SMTP stands for Simple Mail Transfer Protocol. It is a widely used protocol for sending email messages between servers. SMTP works on the application layer of the TCP/IP protocol stack and follows a client-server model.

It works by establishing a connection between a client (email sender) and a server (email provider). The client provides the necessary information, such as sender and recipient email addresses, and sends the email message to the server. The server processes the email, performs security checks, and attempts to deliver it to the recipient’s server. Once delivered, the recipient can access the email using their mail client. SMTP ensures reliable and secure email delivery across different servers and networks.
