Hi,
I got stuck while renewing the ssl certificate of my hmailserver server (on a windows 2022 server). I bought a PositiveSSL / ValidateDomain certificate from Sectigo, which can download in p7b or crt format. I found info to convert it to pem format with openssl, but I have no clue how to get the key file. And mail clients won't connect any more. Last year I managed, but I lost the document that I made for myself describing the process. Can anybody help please?
