Nice try. Here is why I reject this patch.
1) Postfix calls dns_res_query() when res_query() would not provide
the correct result.
2) You are adding code that makes dns_res_query() call res_query().
That is not right, that is not even wrong. It is just silly.
And here is what I will accept.
I will accept a patch that disables the dns_res_query() function
and that replaces the dns_res_query() call with a warning that the
dns_ncache_ttl_fix_enable feature is not supported.
