Hi folks,
I followed the developer's recommendation to use Sp@mX for 30 days. I kept at it because of the claim by the vendor that one month was required for Sp@mX reports to kick-start the various ISP security departments into action against the spammers being reported. Well... kinda. Users (at least this one) don't hear from the ISPs regarding Sp@mX generated complaints. We have no way to know if Sp@mX is performing as advertised.

It seemed there was some tapering off of spam over the last 13 days. The average received for the first 18days was 30 / day. Since then, it has averaged 19 / day.
Only a 37% reduction after the "recommended trial period." The total for the entire 31 days was 789 actual spam messages. This is not good enough.

I think many spammers KNOW they have to move around to different ISPs and when one ISP shuts them down, they move, (probably to a predetermined new email service). Also - remember that "spam" can be sent by computers belonging to "regular people" who don't know their Windows box has been hijacked. Often, this "other victim" only discovers this belatedly. So the spam just keeps on coming, often the same stuff you've been getting for days or weeks. So, the theory behind Sp@mX may be flawed; as the claim states there will be 100% elimination of spam (after a sufficient period).

The other real negative is that there is no way to automate "corrections" - Sp@mX continued to mis-identify 90% of legitimate emails as spam. As previously noted - each time you run Sp@mX, it lists ALL messages still residing on the remote email server - including those you've downloaded and "processed" (meaning read, responded to, deleted, etc.). So there's no "memor" of designated "OK" emails. So the Sp@mX user must carefully review these lists and make sure to identify legitimate emails for every session. This is time consuming and invites errors- if you fail to spot a legitimate email and uncheck it, Sp@mX sends out a complaint on that one too! You CANNOT do this sorting / checking in haste.

Sp@mX does seem to have a limited memory - if you run a 2nd session within a short time after the first run, Sp@mX will remember SOME of the legitimate emails you "unchecked" in the earlier session. But that's not good enough to even say, "OK, I can live with that." It is VERY annoying when I see my sister's emails consistently mis-identified as spam!! After all, her return email address is NOT, "insanemongoose@chiantong.net"

Is Sp@mX worth the 20 bucks? NO - not when you include the cost of your time to eyeball each item in every email download and consider that real screw-ups might occur, causing you to spend even more time on straightening things out. At least Apple's Mail.app filters accurately & consistently - why can't Sp@mX do the same?

Thumbs down on this one, folks. (I won't review this again unless the creator comes out with a significantly better version.)
