No. I think it belongs on -devel. This one is sent there too. Follow-ups on
spf-devel please.

On the libspf's not good is the short answer. Both upstreams are MIA at the
moment. James seems to be definitely gone for good. Wayne is periodically
MIA hard to know how long for. There is one new C implementation being
worked.

The best choice today is libspf2 + the patches in the latest Debian version
for 64bit stability and RFC compliance.

libspf implements none of the RFC processing limits, so I would not recommend
it.
