   Hi, I added a note on source builds in #8 - can you check if that does the trick?

   Possible reason why I’m using podman and not docker? When I ran podman pull ghcr.io/chatmail/docker:main, the process continued. But there’s still an error further down:

   I have tried preparing a branch with bridge mode default, but I'm not sure want to go that way (#9). you could try enabling host mode networking for podman; and I don't know whats wrong with the toml.
