Operating System Selection and Configuration

Pre-built packages are provided for the officially supported platforms listed on the Installing on Linux page. If you build from source, a wide variety of operating systems are possible.

In addition to the officially supported platforms, the following systems have been community-tested:

Rocky (8, 9)
Alma (8, 9)
Debian (11,12)
Ubuntu (18, 20, 22, 24)
OpenSuse Leap (15.4)
Azure Linux (CBL-Mariner2)
Amazon Linux 2
Amazon Linux 2023
Kali (2023.1)
CentOS 7 (obsolete and not recommended)
RHEL 7,8,9
Mariner
Linux Mint (Cinnamon)

KumoMTA works with x86 and Arm processors.

Note that most "dnf" systems work fine with the Rocky install instructions. And that most "apt" systems work fine with the Ubuntu install instructions.
