A mail server, also known as an e-mail server, is a computerized system that sends and receives emails. In essence, it primarily works as a virtual post office. The server stores incoming mail for distribution to users (mailboxes) and sends out outgoing mail. It uses a variety of protocols, including SMTP (Simple Mail Transfer Protocol) for sending, POP3 (Post Office Protocol 3) and IMAP (Internet Message Access Protocol) for receiving.
In the digital age, mail servers have become a crucial part of business operations, enabling swift and efficient communication among team members, as well as with clients and other external parties. Mail servers can be hosted in-house or can be outsourced to a third-party provider. Many businesses prefer to use third-party hosting due to its cost-effectiveness and the technical expertise provided by the host.
The main function of a mail server is to store incoming mail in the recipient's mailbox and to send out outgoing mail.
