... nope, that doesn't work ...
If I go this way ...
hMail- Server -> SSL-Certs -> (any name) ...
Certificate File = ...Abyss\kcstore\5e****a4.acme.crt
Private Key File = ...Abyss\kcstore\5e****eb.key
... I can't connect to the MX anymore :(
I think that hMail need another type of Cert or any other is wrong with it. But at the moment I don't know to fix that ...
BTW:
The files I use are a real domain (Master) and also the MX running on this domain. I also use a global key file for all domains in Abyss so I only have one single key file. Every domain create an own acme.crt and I use definately the right one ...
EDIT say:
I have now create CertFiles at SSL4FREE and that works well. So it's what I have in mind before: The Fileformat or anything else with that out of Abyss don't work with hMailserver this way...
