But it seems the original developer is not involved as much if any anymore in the project and it appears the hMailServer is suffering in that it does not seem to be maintained by updating it to keep up with changes in email such as the new TLS 1.
The maintenance seems to be provided by volunteers from the the hMailServer forums and nothing has been released as a stable production release for hMailServer in over a year. I would like to question you about this and if you have any information about hMailServer maintenance being ongoing. I have seen one person announce they were going to stop using hMailServer because it was not keeping up in its maintenance and were sorry to have to stop using it because it had served well when it was better supported.
I have started looking for a replacement for hMailServer before it becomes too outdated if i need to switch.
