Send mail through internet
Sending mail through the internet is a process known as electronic mail or email. Here's a step-by-step guide on how it works:
Email Sending Process:
- Composition: You compose an email using an email client software (e.g., Gmail, Outlook, Yahoo Mail) or a web-based email service. You enter the recipient's email address, subject, and message body.
- Email Server: Your email client sends the composed email to your email server, which is usually provided by your internet service provider (ISP) or email service provider (ESP).
- SMTP (Simple Mail Transfer Protocol): Your email server uses the SMTP protocol to send the email to the recipient's email server. SMTP is a standard protocol for sending and receiving email over the internet.
- Recipient's Email Server: The recipient's email server receives the email and stores it in the recipient's mailbox.
- POP3 (Post Office Protocol version 3) or IMAP (Internet Message Access Protocol): The recipient's email client (e.g., Gmail, Outlook) connects to the email server using POP3 or IMAP to retrieve the email from the server.
- Delivery: The email is delivered to the recipient's email client, where it can be read and responded to.
Email Protocols:
- SMTP (Simple Mail Transfer Protocol): Used for sending emails from your email client to the recipient's email server.
- POP3 (Post Office Protocol version 3): Used for retrieving emails from the email server to your email client.
- IMAP (Internet Message Access Protocol): Used for retrieving and managing emails on the email server, allowing you to access and manage your emails from multiple devices.
Email Encryption:
To ensure the security and integrity of emails, many email services and clients use encryption protocols, such as:
- TLS (Transport Layer Security): Encrypts the email transmission between your email client and the email server.
- SSL (Secure Sockets Layer): Encrypts the email transmission between your email client and the email server.
Common Email Services:
- Gmail: A free email service provided by Google.
- Outlook: A paid email service provided by Microsoft.
- Yahoo Mail: A free email service provided by Yahoo.
- ProtonMail: A secure email service that uses end-to-end encryption.
Remember to always use a secure and reputable email service to ensure the safety and integrity of your emails.
