Hello,
I would like to use aaPanel to set up a mail server for my domain, but I encounter an error.
I managed to install the plugin, but, from the first step, I encounter an error.
I followed this tutorial, but, at the first step, the panel return to me an error.


For my "Domaine name", i put my domain, and for my "A record" i put my subdomain, which points to the ip of my vps, and which is not proxyed by cloudflare.

Does someone can help me please?
