If you are a corporate Gmail user, get ready for double the email storage capacity and some new security tools.

Google has reworked some components to their online business application suite and doubling email is hot on the list. The current business users, hundreds of thousands of them in the public and private sectors, will see their 10 GB of space jump to 25 GB. The next exciting addition is the inclusion of security features through the recent Postini acquisition. Although Gmail's spam blocker and virus tools are pretty good, Postini's addition is sure to set a new standard in web based email solutions. The new security tools will be able to insulate email from viruses and spam, as well as recover lost data, and also ensure employees are not violating company policies.

Standard Gmail users can expect their storage to hover under the 3 GB point for a while, and as for the security features, no word on whether they will be integrated. The Standard Edition of Google Apps is free, while the Premier Edition with more storage is $50 per user, per year.
