Subject: Fix SPF mx lookup failures.

When A/AAAA records are not included in the MX response, explicitly query
both A and AAAA records, instead of returning A records if they were found;
also query AAAA before A.

MX lookup for an SPF check -- new RFC1035_MX_QUERYALL flag to force
both A and AAAA queries.
