GMail reads and archives mail on its own
igorhvr: At the bottom of the gmail page, you will find text like: "Last account activity: 40 minutes ago at this IP (201.82.153.204)." followed by a "details" link.Click on the details link, and you will see the last IPs from which Gmail activity took place.You will also find a "Sign out all other sessions" that might be useful if your account was compromised - even if you changed your password, if someone was logged in already he will not be suddenly logged out - so he might still retain control of your account.Good luck.
