NethServer Version: 7.8.2003
I have set up DKIM on my Nethserver and it looks like this will work. But when I want to check the status of my mail domain, I see a red warning at port 25 (exit code not zero) and a yellow triangle at IP (MX or IP not found).
Port 25 in my separate firewall is open and points to the NS.
Why is that? Enclosed a picture for a better understanding.
Thanks and Regards …
