I have a Google Apps email (Gmail with my own domain) - let's call it John@example.com.
3 days ago many people in my address book were sent a spam email FROM my John@example.com account.
When I logged into the web app (I use Outlook on the desktop to manage my email) these emails didn't appear in the sent items.
I changed all the passwords but now 3 days later another group spam message has gone out.
Again nothing is in the sent items. It surprises me that these messages are getting through at all if the email is just being spoofed.
How can I get to the bottom of this and stop these messages being successfully sent. How can I know if I've been hacked?
