Hrm. At a guess, something's losing a chunk, but neither I nor our
earlier coverity scan could immediately see it. There is always the
possibility that it's just filling in the DNS cache, and that the jumps
in usage are just finding a free bucket in the open hash table. It's not
climbing drastically. Have you run the system under valgrind? Do you
know how many messages actually hit the milter?

I would be tempted, at this stage, to fold spfmilter into the libspf2
tree, for ease of distribution and installation, but I am not keen to
maintain it. Would you be interested in being a co-maintainer in
subversion if I were to do so?
