Sorry for the late reply. My wife has been keeping me busy with shit I don’t want to do. Looking at the conversation on github, I saw the first suggestion being the inclusion of pimsync into the docker compose file. I’m no developer, but it stands to reason that the same challenges remain if doing this because at the end of the day, pimsync is just a parser to sync with file systems, and for it to work with carddav the other party would still need to support carddav, right? So that idea is dead in the water. I am going to reply now to your 4 questions in the github. My handle is ‘mofongox’.
