Google Spam Filtering with Postini
Dare I say that they have done it again? Has google rewritten the rules for spam filtering for business? Googles press release as of today has some interesting announcements about how they plan to simplify the business of email security and message discovery. Does this mean that my article about spam filtering that was written a week ago completely invalid at this point? Will Spam be cured by the big brains over at Google?
Not exactly What it means is that companies like St. Bernard software, MXLogic and CudaMail will be getting a shake up.
What Google has done is dramatically improved the price point, scalability and reliability of the Software as a Service (SAS) model for email filtering. The way that this works is a company continues to host their own email servers, or they have an ISP that hosts it for them and they send their mail to be sanitized from Spam and Viruses before the content even makes it to the ISP. Think of it like a “super receptionist” that opens each and every piece of mail that is addressed to your office and determines that it is valid before sending it on up to the intended recipients. The problem is her trash can gets filled every day, five…ten…fifteen times each day and it clutters up the office. She does her work extremely well, but the trash lands up in your trash can.

Now imagine that this “super receptionist” is sitting at the post office and she is sifting your mail and determining what should be put onto the truck and delivered to your office. Her job is to sort mail AND to keep your trash (spam folder) almost completely empty. Sometimes she makes a mistake and some spam gets delivered to you, and you open it because you are so used to 99.99% of your mail being valid OR sometimes she misclassifies something important as SPAM and you never get to see it…
Either way filtering your mail at the post office also referred to as the CLOUD is the most efficient way to handle your spam. They update the software and keep all the antivirus rules up to date without the need for an annual software plan from your antivirus vendor.
A little Google propaganda but it is true.
Scanning for Spam in the cloud is my personal choice as a best of breed service, but it does not negate the need for network based antivirus solutions. Its great for SPAM, not always the best solution to protect against viruses and trojans.
Unless you need customized rules for your spam filtering, outbound smtp filtering or specific attachment blocking - go with the basic service.
You can see all of the options at the Google Apps information portal.
My bottom line suggestion: This is the best of breed solution right now. If you don’t have spam protection, sign up and get it. IF you have spam services already SWITCH.
