was using this tool, https://toolbox.googleapps.com/apps/checkmx/, to check my domain and it reports this error:
Every name server must reply with exactly the same TXT records.
my domain has multiple TXT records and a dig check verified that all the name servers respond with all of the TXT records, but not in the same order. otherwise the records are exact matches. in fact the tools itself shows the records and they are exactly the same. so the response order must be the trigger here.
but is that really an error? doesn't seem right.
