According to a Google announcement HTTPS encryption has been introduced that keeps your mail secure as it travels between your web browser and Google Mail servers. The feature will now disallow someone sharing public wifi from maliciously reading your mails.

HTTPS by default

Google has introduced HTTPS encryption that keeps your mail secure as it travels between your web browser and Google Mail servers, so someone sharing your favourite coffee shop's public wifi can't maliciously read it. Banks and credit card companies use this same protocol to keep your online accounts safe.

To protect your Google Mail account, Google has turned on the option to "always use HTTPS" for everyone. This added layer of security can make Google Mail slower, so if you don't use unencrypted wireless connections, you can choose to disable this option in your account Settings.

"Even if you change this setting, Google Mail will always encrypt the login page to protect your password." the announcement said in Bangalore on Friday.

More storage

For users how need more space space for your email and photos, Google has introduced 20 gigabytes of storage for only $5 a year. Extra storage is shared between Google Mail and Picasa Web Albums and acts as an overflow if you use up your free storage.

New in Labs: "Got the wrong Bob?" and "Don't forget Bob"
Ever included Bob (your boss) instead of Bob (your friend) on an email by accident? Oops! Turn on "Got the wrong Bob?" and Google Maill will check if you meant to include Bob Smith rather than Bob Jones based on the groups of people you email most often.

With "Don't forget Bob," you can start composing an email to a group of people, and Google Mail will suggest other contacts you might want to include. Check out these experimental features and more on the Labs tab under Settings.

Four more themes
