What is it?

iRedMail is a complete mail server stack that installs on mainstream Linux and BSD systems. It is aimed at administrators who want to run their own email service without assembling and configuring each component by hand.

The project supports CentOS Stream, Rocky Linux, AlmaLinux, Debian, Ubuntu, FreeBSD and OpenBSD, with specific release versions listed for each. Installation follows the project's published guides, and the maintainers note that the guides should be followed closely. Packages come from official yum repositories and EPEL, with patched RHEL/CentOS source packages published separately.

For larger or less technical deployments, the project offers a paid platform with one-click upgrades and ticket-based support, along with an all-in-one Docker edition maintained in a separate repository.
