Ah, I see. Looks like some other people in this thread gave you some good info, I’ll have to keep this in mind if I ever need to change my approach. Happy to hear you got a good answer!

My solution to this was a radicale docker container, with DAVx5 on f-droid. Very lightweight, just works without much configuration needed. I don’t use my phone for email much, so I just use thunderbird for my email client

Would love to deploy this, but unfortunately I’m running server equipment that apparently doesn’t support MongoDB 5 (Error message MongoDB 5.0+ requires a CPU with AVX support, and your current system does not appear to have that!). Tried deploying with both 4.4.18 and 4.4.6 and can’t get it to work. If anybody has some recommendations, I’d appreciate hearing them!

Edit: Changed my proxmox environment processor to host, fixed my issue.
