Mail Transfer Protocol

Mail Transfer Protocol (SMTP) is the system that allows email messages to travel across the internet from your device to the recipient's email server. Think of it like a digital postal service: when you send an email, SMTP helps deliver it to the recipient's email server, which then makes it available for the recipient to access later. It handles the sending process reliably, ensuring your message reaches its destination, while coordinating with other protocols to fetch and display your email on the recipient's device.
