lippf_alt works fine for me. Beside potential problems with libspf, the
key point is to link with a thread safe resolver. libspf and libspf_alt
make DNS querries within milter-greylist, and milter-greylist is a 
threaded program. If the resolver is not thread safe, you crash at the
first time two thread make a DNS query at the same time.

I don't agree. Spammers operating from fixed network just deserve an entry in 
your blacklist. SPF doesn't change anything to that.
