What is a Mail Server?

Before we dive into the details of how to host your own mail server, let’s first understand what a mail server is. A mail server is a computer program or a physical server that sends and receives emails over the internet. When you send an email, it is sent to the recipient’s mail server, which is responsible for delivering the email to the recipient’s mailbox.

There are two types of mail servers – inbound and outbound. An inbound mail server receives incoming emails and delivers them to the recipient’s mailbox, while an outbound mail server sends outgoing emails to other mail servers.
