Key facts:
- hMailServer is a mail server supporting SMTP, IMAP and POP3 with multi-domain hosting. It was originally created by Martin Knafve.
- Progressive Robot Ltd, of Chester in the United Kingdom, forked hMailServer in 2026 and maintains the hMailServer 6 line. The original project has since resumed development separately.
- Current release: hMailServer 6.3.7, released 17 October 2026.
- Platforms: Windows 10 (version 1607 or later), Windows 11 and Windows Server 2016 or later, x64, with a preview installer for Windows on ARM64 from hMailServer 6.3.6; and Linux since hMailServer 6.3.0, on x86-64 and AArch64. From hMailServer 6.3.6 each release carries a generic .deb and .rpm and a package for each of Debian 12 and 13, Ubuntu 24.04, Fedora 43 and 44, Enterprise Linux 9 and 10, and openSUSE Leap 16.0 and Tumbleweed, two AppImages and a container image, registry.gitlab.com/hmailserver/hmailserver.
- Licence: AGPL-3.0. Free, with no per-mailbox fees and no paid tiers. Managed services are available from Progressive Robot.
- Upgrades: hMailServer 5.3 or later upgrades in place to the current release. A server on 6.3.4, 6.3.5 or 6.3.6 installs the current release, hMailServer 6.3.7, by its live update, with the exceptions the 6.3.7 announcement lists under Upgrading; one from 6.2.28 to 6.3.3, or from 6.3.3's AArch64 packages or AppImages, upgrades by hand once, and any older server runs the installer.
