Download and Install iRedMail

Download and Install iRedMail on Ubuntu 20.04 LTS

iRedMail includes all the required packages for the email server where you don’t need to install them separately. We recommend installing iRedMail on empty new server to avoid conflict with the preexisting packages.

To install iRedMail, your server needs a minimum of 2 GB of RAM to work flawlessly as it contains many components. For this purpose, you can rent a VPS with great specs starting from 8 GB RAM for only €4.99. We tested installing iRedMail server there and the performance was just perfect! Before installing iRedMail, you should fix DNS settings by referring to our DNS Settings article. Let’s do the following now:

16. Reboot your server to enable all mail services. If you don’t reboot it, the service will not work. Run the below command.

root@mail:~/iRedMail-1.3.2# reboot

After rebooting your server, PuTTY session will be inactive, so you need to close it and start a new one. The server will take about 1 to 3 minutes to reload. So, please wait before starting a new session. In case you don’t get connected, it means the reboot is not yet finished so wait and try after some time. Once the server is up, you can test the email server by login to Roundcube webmail and other admin panels.

The installation is complete but in the next steps, we will install TLS certificate, improve email deliverability and add extra email domains if you want.
