I have a mailserver running on the Host, where lemmy is installed.
Since a time, i didn’t know when, i can’t send emails from lemmy anymore.
Connection refused.
It is an exim4 configured as satellite listening on localhost:25.
I configured exim to allow also connections from 172.17.0.0/16 and listen on 172.17.0.1 too, which is the docker-bridge ip.
Are there any ideas, how to configure docker or the docker-compose.yml?
telnet is not installed in the container. I tried you command… but error. ls /dev/ lists no tcp directory…
