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.
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.
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
