I already posted of lukewarm review of that software in which I had serious worries about the lack of safeguards in the interface, and the fact that the program takes a bit of attention and care setup, while other competing products are more "set and forget".

Worse, the program had a bug that caused it to add thousand of categories to Entourage's message DB, making Entourage take forever to open.

I did write those concerns to the programmer, who responded about a day later with a fix for my message DB, and an improved upgrade of SpamSieve, and more is on the way.

So in my view, if the program still requires a bit more attention than I would like to put in a spam filter, I could recover my DB back and the most critical interface concerns have been fixed.

And if I compare with bigger companies poor tech support, and the fact that this programs does a really good job at catching spam... here's five stars well deserved :)

And now I can say that I would recommend this program to anyone who's not satisfied with the built-in capabilities of his email client and is willing to put some time in correctly setting-up and training the software.
