UCS Let's Encrypt with Kopano IMAP


Refering to these posts listed below I would like to use the working Let’s Encrypt Certificate for Kopano and IMAP SSL.

I’m not sure, which certificate I need to add to the config (or if I need to convert any of the existing). Any solution is welcome.

(possibly a solution, but unfortunately not explained)



this one?


Thanks, that helped me - I don’t know, why I didn’t find this topic before (and yes, I used the search - maybe the heat).
