Types of https://acortaz.eu/que-es-un-servidor-de-correo
Mail servers can be categorized based on their functions and protocols. Here are the main types:
1. SMTP Server (Simple Mail Transfer Protocol)
- Function: Handles outgoing emails.
- Role: Ensures emails are sent from the sender to the recipient’s server.
- Example: When you send an email, your email client communicates with the SMTP server to deliver the message.
2. POP3 Server (Post Office Protocol 3)

- Role: Downloads emails and typically deletes them from the server after retrieval.
- Example: Ideal for users who access emails from a single device.
3. IMAP Server (Internet Message Access Protocol)
- Function: Synchronizes emails across multiple devices.
- Role: Stores emails on the server, allowing users to access them from any device.
- Example: Perfect for users who check emails on smartphones, tablets, and computers.
4. HTTP Server
- Function: Allows users to access emails via web browsers.
- Role: Provides a web-based interface for email services.
- Example: Webmail services like Gmail and Yahoo Mail use HTTP servers.
