Had a server with Ubuntu 16.04 where a partition filled up. Decided to setup a newer Ubuntu 18.04 server with ISPConfig and utilize the migration tool to move things over. I had e-mail forwarding setup and noticed it's no longer working on the new server. Is there a troubleshooter for something like this? It was working until I migrated it to the new server.
I checked the mail log file but am not sure why it's not working still.
