Is anybody familiar with Spam Arrest? I received this from a person I know and he uses it. Was wondering if it works, if so is it worth it. The link to their homepage:

Any thoughts on it. Seems reasonable to me in terms of cost.

It might be okay if you want to put it on a personal mailbox. If you use your inbox for any sort of business, systems like this are a good way to drive customers elsewhere.

Challenge response systems were popular a little over a year ago but have lost steam. I run the web division of my company and we send and receive 900-1200 emails per day. We had to make a business decision and we decided that when we get challenge response emails, we delete them. We just don't have the time to handle them. If you use it, be prepared to not receive email confirmations from your purchases, inquiries etc. online.

At the annual conference last May that our Email Service Provider runs, over 90% of companies ignore challenge repsonse emails and just delete them.
