What is a Mail Server?
As a user, we all have some experience with email clients like Microsoft Outlook or Thunderbird. But when you go from being a user to trying to start your own business, you will come to see the other side of emails: mail servers.
A Linux mail server software is used for transferring emails from one point of the Internet to another. Also known as Mail Transfer Agents (MTAs), they receive incoming emails from other servers before forwarding them to the user’s client software and vice versa. Although almost all mail servers handle both incoming and outgoing emails, the two functions are separate and follow different protocols. An incoming mail server usually operates using the Post Office Protocol 3 (POP3) or the Internet Message Access Protocol (IMAP), while Simple Mail Transfer Protocol (SMTP) is used to send the emails they have previously received from the user’s client software.

What Are the Requirements for Hosting a Linux Mail Server?
The advantages of hosting your own mail server are improving the security and privacy of your emails and performing email marketing campaigns more effectively. A Linux distro is the perfect choice for hosting mail servers as Linux is lightweight, highly customizable, and doesn’t take much of your hardware resources. Even with a Linux OS, you still need a whole other computer with enough storage and memory resources to act as your mail server. Now, buying a computer with the right specs can get expensive. That’s why hosting your mail server on a VPS is a great option.
