A while back Google bought Postini which provides hosted message security and compliance solutions. I’ve been using Postini for anti-spam filtering and I’ve been very impressed with it. Firstly there is no noticeable delay in delivering valid email and it is pretty accurate in determining spam and keeping upto date with new attacks. It has been very robust and reliable and with over 12 months use I have no problems to report.

You can buy the services directly through Google Apps from $12 per user per year. If you only need inbound filtering then you can buy it for $3 per user per year.
