There are not only potential problems with libspf but existing ones:

| $ spfqtool -s user-support5@... -i 84.97.1.113
| You didn't give me a helo host, using (nobody)
| Segmentation fault


This is caused by code like:

| rr_data = malloc(...);
| ... no initialization of 'rr_data' ...
| strncat(rr_data, ...);

at several places. Really nothing, which I would use somewhere in the
near of a productive system.

A domain + TXT entry are much easier/cheaper to get than a fixed IP.
