I know you are using Gmail for many days. You may love it And you also think that it's quite secure. Yes, it is. I think you have noticed that when u login to your Gmail account you type http://gmail.google.com in your favorite browser's address bar. U have noticed that the login page is secured(You can see the lock icon in your address bar)so that your user name & password are transfered to Google server after encrypting. But just after you login u will see that your inbox is not secured!! Because the site is not secured any hacker can hack your inbox now. If you want to secure your inbox then you have to do the following....
There is a difference between http & https. Later is secured. When you type http://gmail.google.com, Google automatically redirects that site to https://...... so that your login becomes secured. Now if you type http
s://gmail.google.com for your login then after logging in you will see that ur inbox is also secured.
Here is the proof
Non-secured inbox

Secured Inbox

So don't use http://gmail.google.com. Use http
s://gmail.google.com.
I suggest that you make a bookmark of secured gmail site.....
Happy surfing....
