Strange - I received four copies from Davide's server, all delivered about 5 minutes apart, though the headers show that Davide's list server received all four from Arron's gmail account at exactly the same time, "Wed, 21 Mar 2007 17:30:50 -0400". Interesting. Oh well, unrelated to Arron's issue anyway.
