Domain MX not resolving in 1.1.1.1

Hello! The domain lacare.org is not returning any MX records in your DNS. It does on 8.8.8.8 and from the root servers.

I am not sure why this particular domain is not resolving properly, it is not my domain, but we are trying to send email to it and using your servers for DNS resolution.

Adding additional info in another post “new users are only allowed 2 links in a post…”

Hi, the upstream nameserver is misconfigured to return that only NS SOA RRSIG DNSKEY NSEC3PARAM exist:

$ kdig @ns1.lacare.org lacare.org HINFO +dnssec | grep NSEC3
l5mus2obnb0mnnurbl45b2qi8i8ih7ho.lacare.org. 86400 IN NSEC3 1 0 1 6EDA1E27E8BD07D0 l5mus2obnb0mnnurbl45b2qi8i8ih7hp NS SOA RRSIG DNSKEY NSEC3PARAM

But other types such as MX clearly exist:

kdig @ns1.lacare.org lacare.org MX +short
5000 backupmx1.mail.cogentco.com.
100 lacsmtp3.lacare.org.
5 lacsmtp.lacare.org.
10 lacsmtp2.lacare.org.

I’ll try to reach out to the domain owner.

It is working now! Not sure if you changed anything or if the Admin on the domain responded. Thank you for your help. It definitely builds confidence in using Cloudflare DNS when we can get responses to issues in a timely manner.
