Hello,
I have an up-to-date installation of mailcow-dockerized, and I’m trying to restore it to a new server. I’ve tried several times on Ubuntu 22.04 and a Debian 12 destination servers. Both times, the server seems to come up and work, but there are SMTP errors in the logs and I can never send emails. I follow the directions in the documentation for restoring exactly, and I use clean, fresh-install systems. I’ve tried it about 4 times, and failed every time. That’s why I’m reaching out now.
So I’m asking for any advice by anyone who’s had issues like this, and what logs I can collect to help troubleshoot the issue. I’m hoping it is something simple, so thanks in advance.
