This post explains it, but it is still too complicated for me to figure out: https://doc.dovecot.org/2.4.0/installation/upgrade/2.3-to-2.4.html

I had dovecot running unencrypted IMAP via Tailscale VPN, but with dovecot version 2.4.0 it did not accept my configuration anymore. can you share an easy example?
I was thinking of switching to mailcow so i do not have to configure dovecot myself...
I kind of followed the tutorial, but changed the tailscale configuration to how it is advised by tailscale in their blog about tailscale in docker. It is running fine for me.
compose.yml:
services:
nextcloud-aio-mastercontainer:
image: nextcloud/all-in-one:latest
init: true
restart: always
container_name: nextcloud-aio-mastercontainer
volumes:
- nextcloud_aio_mastercontainer:/mnt/docker-aio-config # do not change
- /var/run/docker.sock:/var/run/docker.sock:ro # do not change

Caddyfile:

}
The manual istall now seems too cluttered for me, aswell as the caddy webserver configuration. The AIO probably has an more up to date configuration which is vetted by the community.
I will try to configure the AIO version how i like it, but still apply what i have learned connecting tailscale (https://github.com/nextcloud/all-in-one/discussions/5439)
@BakedCatboy@lemmy.ml your example helped clarify the network and service linking, thank you.
So that means i need to link the webserver to the tailscale service
network_mode: service:tailscale
And also add the tailscale to the "proxy" network that is created (like also done in the aio example with
networks:
- nextcloud-aio
)
Molly-FOSS is awesome and it now has UnifiedPush support built-in!
