hMailServer is no longer being actively developed.
The latest major version was released several years ago and since then only critical updates have been released. hMailServer relies on algorithms which are considered insecure by modern standards, such as SHA1. For that reason, it's recommended that you migrate to an alternative software or service.
There are currently 2 tracks of hMailServer:
- hMailServer 5.6.x. hMailServer 5.6.x will continue to receive patches for critical bugs. No new features will be added.
- hMailServer 5.7. hMailServer 5.7 is in beta and is maintained by 3rd party contributors. While in use by beta testers, there are currently no plans to create an official stable release of it.
It is not possible to purchase commercial support for hMailServer.
