Validating an SMTP server

[Hoggins!]

Hey there !

I'm trying to validate my DANE records against my SMTP server, but I'm
facing something that I cannot understand, because I believe I'm lacking
some details about the validation failure : I'm trying to validate
smtp.hoggins.fr. It gives me an error on the validator
(https://dane.sys4.de/smtp/smtp.hoggins.fr), but I don't know what I
need to change about that.

Is there a way to be more verbose about the validation failure ? Maybe
some client-side checking I can do manually ?

Thanks.

    Hoggins!
