mail server

A **mail server** is a specialized computer or software system responsible for sending, receiving, and storing email messages. It plays a crucial role in managing email communication by handling the transfer of emails between users and domains. Mail servers typically use protocols such as SMTP (Simple Mail Transfer Protocol) for sending mail, and IMAP (Internet Message Access Protocol) or POP3 (Post Office Protocol) for receiving and retrieving mail. Proper configuration and maintenance of mail servers ensure reliable, secure, and efficient email delivery for both personal and business use.
