This server does not have IPv4, only IPv6 so ZoneMTA seems to fall back to using IPv6.

Do you have set ignoreIPv6:true in your zone options? This should disable IPv6 checks.

I have ignoreIpv6 = true.
Is it case sensitive ?

Yes, all options are case sensitive

IPv6 related settings are:

  • preferIPv6 - if true then tries AAAA first and falls back to A if not found. If false then checks A first and falls back to AAAA if not found.
  • ignoreIPv6 - if true then does not check AAAA record even if A is not found.
