Now that Apps for Education is getting Postini features, Google will stop offering new K-12 school customers Postini's Google Message Security package.

Eventually, once Google Apps has a native set of e-mail security features comparable to the ones in Google Message Security, they will have to use the ones in Google Apps.

"Google Apps for Business and Google Apps for Government customers are welcome to try these new features but will not be required to transition until a later date next year," the blog post reads.

Analyst Rebecca Wettemann, from Nucleus Research, liked the move. "In principle, simplifying e-mail security policies is a good idea -- less work for administrators," she said via e-mail.
