Google has purchased Postini. Over the winter I re-architected Pixel Mechanix web services and after looking at how my servers and I were spending our time, I realized that the bulk of that was on fighting spam: Keeping up with blocklists, researching blocked emails for my clients, and adjusting filters.
This was taking a toll on me and my servers. I have never charged for email and have included it as part of the web hosting packages, but I made the tough decision to start and I cut a decent deal to bring Postini to my clients.
It has helped tremendously and while there are a few spams that make it through the filters, it is a rare exception. Any mail that is blocked gets put in a quarantine and people get an email listing them so that they can retrieve messages that they need to.

Users can tune their own filters, block lists, and white lists.
Taking aim at one of Microsoft’s core franchises, Google said that it would acquire the e-mail security and management company Postini for $625 million in cash.
Here’s hoping they don’t change a thing. Postini has a great thing going.
