Operating System Selection and Configuration

KumoMTA was built from the ground up to be extremely flexible infrastructure. We have built standard package builds (AKA repo install) for the most commonly used Linux Operating Systems, but if you build from source, a wide variety of Operating Systems are possible.

So far we've run non-production tests on the following systems:

  • 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 (2003.1)
  • CentOS 7 (obsolete and not recommended)
  • RHEL 7,8,9
  • Mariner2

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.
