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 ?
it does not have MX, that's why.
However, anyone should reject mail from it because:
gmail.dk. 300 IN TXT "v=spf1 -all"
_dmarc.gmail.dk. 300 IN TXT "v=DMARC1; p=reject;
rua=mailto:mailauth-repo...@google.com";
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 58935
;_domainkeys.gmail.dk. IN ANY
so: deny based SPF, no DKIM key, DMARC reject.
however, they miss the nullmx record:
gmail.dk. 300 IN MX 0 .
