What do you mean with shorthost here?
Most servers I know use shortname to be without dots in them (official debian spec, for example).
I would assume DANE requires the FQDN, not the subdomain "mail" or "my" or something..
/etc/hostname is "mail" or "my" in my case, hostname -f is the FQDN, for which the cert exists.
Also, for cloudflare, you have < > brackets in your config example;
<cloudflare login (e-mail)>
are they needed, or do they just portray an entry?
