What is Debian?

Debian is highly customizable and has a vast repository of software packages, making it an excellent choice for hosting a mail server.

The Basics of Debian Hosting

If you are new to Debian hosting, here are some basics that you need to know. First of all, Debian is a command-line based operating system, which means that you need to have some knowledge of using the terminal to manage it. However, many tools and web interfaces such as Webmin allow you to manage your mail server without using the command line. Also, Debian is known for its stability, which makes it an excellent choice for a mail server that needs to run 24/7.
