Postini Retires to Make Room for Google Apps

We can no longer offer Postini spam testing, as our Postini services have been migrated to the ‘Google Apps’ filter. Google purchased Postini in 2007, and stopped renewing contracts for Postini in 2012.

Now most companies that used Postini are transitioning to Google Apps or one of the alternative spam filters. Learn more about it here.

It’s actually not as bad as it might seem. This blog is the first in a series which will take you through it step by step.
