Reindl, See RFC 4406, The format Ive used, which was recommended by an old hotmail postmaster website guide a few years back, when we had delivery issues to them (like everyone else) was essentially TXT "spf2.0/mfrom,pra <same data as spf1>" I only use spfv1 for the SPF RR. passing comment - nice to see finally they fixed up openspf.org, which was dead for a very long time, had to alter my spf.pl's to use .net which did not fail.
