Fantastic review, Innuendo. I've been using AntispamSniper for over a year now, and it definitely generates less false positives and false negatives than PopFile, which I had used before - and PopFile was already pretty good. The toolbar is nice to have, and the configuration really needs very little maintenance.
Without ever tweaking the weighting, AntispamSniper gets almost everything right. Sometimes it's a bit hard to teach it very short messages (one-liners) as spam, and it takes a few of those before AntispamSniper learns to recognize them - but like I said, I've never bothered to tweak the filtering options.
My favorite feature of the shareware version is the automatic whitelisting of recipients in outgoing mail, really handy. Other than that, the freeware edition is probably fine for most uses.

(check your DonationCredits) I have always held a "worker is worth his wages" and you obviously put a lot of work into this review. I enjoyed reading it very much. Given this is only your first review, perhaps you should consider developing your technical review skills to a professional end? One of the most important aspects of writing is the ability to do so using what is called your, "real voice." As I read your review, I could "hear" you "speaking," even though I have never really heard the sound of your voice. Many at DC possess this ability, but f0dder, Darwin, Mouser, zriddling, app103 and Wordzilla excel in "speaking" in their missives, but I digress. 

using it under Windows 7 64 bit with Outlook 2007 and my wife is using it on XP Pro 32 bit with Outlook 2007. It's been working great on both systems.
