E-mail, or electronic mail, is an electronic method of communication that enables the exchange of messages, documents, files and information between people via computers and the Internet.

A mail server is a server program that takes care of receiving, storing, delivering and sending e-mail between users or domains.

The main components and functions of a mail server include:

  • Receiving mail: The mail server receives email messages from clients (eg email clients such as Outlook, Gmail, Thunderbird).
  • Mail delivery:The mail server ensures the delivery of received messages to the appropriate e-mail addresses of users or other servers.
  • Message storage:A mail server stores received and sent messages and other email data on the server or external storage.
  • Sending mail:A mail server allows users to send email to other users or domains via Simple Mail Transfer Protocol (SMTP).
  • Authentication and Authorization: Ensuring the safety and security of e-mail with mechanisms to verify the identity of senders and determine who can send and receive e-mail.
  • Filtering and antivirus protection: Dealing with spam, identifying malware and malicious attachments.
  • Synchronization: Enable synchronization of email, contacts, calendars and other data between different devices and clients.
  • Settings and configuration: System administrators set up and configure the mail server based on the needs of the organization or individual. Each organization or email service provider may have their own specific settings and additional features depending on their requirements, security practices and infrastructure.
