 ### 4. **Commands and Responses:**
 - SMTP communication involves a series of commands and responses between the client and server. Common commands include `HELO` (client identification), `MAIL FROM` (specify sender address), `RCPT TO` (specify recipient address), `DATA` (begin message data input), and `QUIT` (terminate the session).
 ### 5. **Relaying:**
-- SMTP allows for the relaying of messages between different [email](eMail.md) servers, facilitating the delivery of [emails](../../../Server/eMails.md) across different domains.

 ### 1. **Live Operating System:**
 - Tails is a live operating system, meaning it can be run directly from a USB stick or DVD without the need for installation on a computer's hard drive. This enables users to use Tails on any computer without leaving any footprint on the host system.
 ### 2. **Privacy and Anonymity:**
-- Tails routes all internet traffic through the [Tor](../internet/Tor.md) network by default, providing users with anonymous and censorship-resistant access to the internet. It also includes cryptographic tools for encrypting [emails](../../../Server/eMails.md) and files, enhancing user privacy.

 ### 3. **Amnesic by Design:**
 - Tails is designed to be amnesic, meaning it forgets everything about the user's activities after each session. Once the session is closed, no data is stored unless explicitly saved to an external drive.
