How Email Servers Work

SMTP: Sending Emails
Simple Mail Transfer Protocol (SMTP) sends outgoing mail. When you click "send," SMTP springs into action. Your email client connects to an SMTP server. This server then routes your message. It finds the recipient's mail server. Finally, it delivers the email there. This process happens in milliseconds.
The SMTP server acts as an intermediary. It authenticates the sender first. Then, it checks the recipient's address. If valid, the transfer proceeds. If not, an error message returns. This ensures proper delivery.
