DNS not fully propagating

Maintenance
3
  1. My aim was to use MIAB as a mail server, everything else was default except for the DNS in pt3, and I would not have touched it if it did not keep failing, to answer your question, it should be using MiaB as DNS, not external DNS
  2. Domain is ssdmeter.com
  3. I only changed my MIAB’s DNS because lookups kept failing on the status page Errors on my system status checks page on v65 - #10 by miaber
  4. DNSSEC is not enabled
