i recently begin to see domains give connection timeout

posttls-finger -l none gmail.dk

According to my DNS, gmail.dk has no MX record. Is that expected?

in what way its not a nullMX domain ?

postfix deliver mail to A/AAAA aswell if existing, i have custommers 
that had sent mail to this domain, so it possible google did not remove 
the A/AAAA or just miss to add rfc 7505 ?
