Mail servers are computer systems that send, receive, and store electronic mail (email). They use protocols like SMTP (Simple Mail Transfer Protocol) for sending, and POP3/IMAP (Post Office Protocol version 3/Internet Message Access Protocol) for receiving. They are a fundamental component of email communication, handling the routing and delivery of messages between users and domains. Common uses include personal and business email communication, automated notifications, and marketing campaigns.
