What is a mail server?

What is a mail server?
A mail server, or e-mail server, is a program that is a key element of an e-mail system. It works like a post office, receiving, processing and delivering emails.

Here's a simplified explanation of how a mail server works:

  1. You write a letter and press the "Send" button.
  2. Your email client (the program you use for email, such as Outlook or Thunderbird) connects to your sender's email server.
  3. Your sender's mail server receives the letter and sends it to the recipient's mail server.
  4. The recipient's mail server delivers the mail to the recipient's mailbox.

There are two main types of mail servers:

  • Incoming mail servers: Store e-mails intended for recipients.
  • Outgoing Mail Servers: Send emails from sender servers to recipient servers.

Mail servers can also be classified by the type of software they use:

  • Open source mail servers: free and publicly available to all.
  • Proprietary mail servers: developed and sold by private companies.

Here are some popular examples of mail servers:

  • Open source mail servers: Postfix, Dovecot, Zimbra
  • Proprietary mail servers: Microsoft Exchange, IBM Domino, Google Workspace

Which type of mail server is right for you depends on your needs.

  • If you need a simple and free mail server for personal use, an open source server is for you.
  • If you need a more powerful and reliable mail server for your business, a proprietary server may be right for you.
  • If you need a server for personal tasks and you need to know its cost, go to the DELL Server Configurator link .
