I have gotten a few responses now on the spamass-milter mailing list, but none of them is from a project member or maintainer.
I have put a copy of the spamass-milter source at https://github.com/andybalholm/spamass-milter. Feel free to file issues or pull requests there. If/when a spamass-milter project member takes an interest, changes can be merged back into the official CVS repository. Andy
