I met with Mark [1] (and JeffK) for dinner tonight as payment for helping to get the greylist daemon [2] running on his system. I was glad to do it, if only to keep me honest in my code; Mark's system is a 64-bit version of OpenBSD on a non-Intel platform, and it took a few days (since I didn't have direct access to his systems and we were communicating via email) to get it mostly working (there are apparently a few details I still need to iron out).
