I went through another 24 hour period of spam and it looks like Project: LOOPBACK SPAM [1] has cut the spam down a bit—only 194 spams from the last 24 hour period. I don't know if this is due to setting the backup MX (Mail eXchange) server to 127.0.0.1 or the natural ebb-and-flow of spam. I'm hoping the former since in the past two weeks or so we've been inundated with spam problems at The Office.
