Hello, I’ve juste enable DANE and https://dane.sys4.de <https://dane.sys4.de/> is green when I test my domain numeezy.com <http://numeezy.com/>. Also postfix SMTP client says "Verified TLS connection established to mail-in-1.numeezy.com[188.165.154.163]:25: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)"
Maybe some DANE expert here can definitely confirm that my setup is sane. Thanks for your feedback. Alexandre
