Looking back over this thread, despite all the chatter about libspf and
libspf2, one thing from spf-help that doesn't appear to have been
mentioned on spf-discuss is that the SPF implementation being used by the
original poster is, "Michael Brumm's SPF filter on W2003 SMTP server".
The original poster on spf-help doesn't appear to have gotten a clear
answer to his question (other than your SPF record is fine, it's a bug).
Michael Brumm's SPF filter uses libspf2 (as he writes on his website).
So if the unpatched libspf2 is used, the bug is also in Michael Brumm's SPF
filter.
