What is the point of dns_naptr_ignore_rfc default value:
dns_naptr_ignore_rfc
If the DNS lookup should ignore the remote side's protocol preferences,
as indicated by the Order field in the NAPTR records and mandated by RFC
2915.
dns_naptr_ignore_rfc = yes | no (default yes)
In my (and RFC 2915's) opinion the default should be 'no'.
