Hello,

the DANE SMTP validator is great! Thank you for providing it. I wish it had been around at the time I enabled DANE ;-)

I'm using delv and posttls-finger to monitor DANE/DNSSEC in the icinga2 monitoring system. I just uploaded the nagios plugin scripts to github and wrote 2 blog posts about configuring it.
