The other ones are just easy-to-remember names for access to your emails.Ĭhanges may take up to 24 hours before applying. MX is mandatory to receive email on your Raspberry Pi. Now you need to go to your domain name registrar and change these zones to match your current IP address (or your dynamic DNS provider domain name): It’s not the perfect option for an email server because you’ll have small downtimes when your IP changes, but if you’re not too serious about your emails, it should be fine. If you don’t have a domain name, I think that you can use this alias directly.

You’ll have to install a tool to regularly give them your current IP address, and they will redirect a domain like to your last known IP address ( more details about this here). If you don’t have a static public IP address, you will need to use a free dynamic DNS service like No-IP to redirect a domain to your dynamic IP address. In the next steps, we will change our domain name DNS settings to use our IP address as the mail server. Setting up additional security features such as a firewall or fail2ban service is also a good idea. So be sure to follow this tutorial precisely, and then monitor the system logs to make sure that you are the only one doing the actions that occur on your server.

If you need help to set up SSH on your Raspberry Pi, click on the link to learn everything about this protocol and how to use it. I suggest you use SSH to follow this tutorial from your usual computer and copy/paste commands and configurations (there are a lot of them!).

A static public IP address (or at least one dynamic DNS service).Īlso, know that I make this tutorial on Raspberry Pi OS, so I recommend installing Raspberry Pi OS first (Lite will be enough) by following this tutorial.

A domain name (I will use in all the steps below, don’t forget to change it).But if you want to use an SD card you can, I did a benchmark of the most popular SD cards here. A micro-SD card or USB key: I tend to use SD card less and less, and use this USB drive from SanDisk instead for all my experiments.A Raspberry Pi: Any model should be fine, but I would recommend a Raspberry Pi 4 or at least a Raspberry Pi 3B+.If you want to follow the tutorial until the end, you will need: If you want to set up an SMTP server, the requirements are almost non-existent.Ī Raspberry Pi and an SMTP server that will serve as a relay is sufficient (Gmail for example).
