When I try start the container I get a

Try to set RELAY_USE_TLS to "no".

for me that worked because it seems it always requires some Certifiacte file and the mentioned default location is empty in the container. and RELAY_USE_TLS is by default set to "yes".

Not sure if it then falls back to an unsecure connection though.
