We’ve been testing Baraccuda’s new BRBL spam block list at work. This involves flagging but not actually blocking messages, then me looking through the logs for potential false positives. I’ve found several, including the Star Wars Fan Club (I subscribed myself just to verify that it was really sent by a server at lucas-online.info) and a senator’s mailing list.
There’s also a lot of definite spam, and a lot of stuff that I just can’t tell. It’s marketing, certainly, but I have no idea whether the particular users actually subscribed or not.
Anyway, this subject showed up several times on the list:
Stimulate your bottom line with Microsoft Financing and the 2008 Economic Stimulus Act
Naturally, when I first skimmed the list only the first three words were visible.
