SILVASURFER  As a registered user I have been using this app now for close to 18 months and nothing comes close to it for spam catching & protection. No it won't solve all your spam issues (what does?) but it is the best mac program out there. Recommend to all my friends who have switched and or bought new macs and they are very impressed. Constantly update, good documentation and a responsive developer.

A must have app for you Mac!  (Version 2.7.1)

FRYE  I've been using this for a while with Entourage, and as others have said, it is simply the best protection you can find for your inbox. Between my service provider stopping spam at the source (so I never have to see it) and SS stopping the ones that trickle through, it is truly a time-saver. Like many people I have different email accounts for different purposes, so spam can and does get unruly. SS is the only solution I've found that makes a difference.

While it is difficult to set up (you definitely need the help guide), once done it basically runs on its own. I think the price is a little steep, and would recommend the developer charge $19.99, but I can also understand wanting to get compensated for the blood and sweat that went into creating the application. I think at a lower price point, they could sell even more copies, which in turn will take an even larger bite out of the spam inundating inboxes everywhere.  (Version 2.7)

EDMUND51  Found this application via a google search.

I just convert from PC to mac and had a similar product.

I can't tell you how much well it works.

I have multiple web pages that had my email address listed on them. On any given day I receive somewhere around 500 emails only 30 or so are not spam.

After I installed SpamSieve 99.99% of the junk goes in the spam box.  (Version 2.6.6)

F451  I have so tried so many of these applications throughout the years, but SpamSieve is the definitive spam filter application. Excellent support, and application.  (Version 2.6.6)
