When looking through the inbox lately, I would find messages in the spam folder with the sender address being the same as mine (“me” in the case of Gmail). In fact, I have also seen the same for my other accounts. I don’t remember what triggered this to happened, but one thing’s for sure is that I haven’t entered my email address anywhere other than to sign in recent days and all are web-based providers (eg. Yahoo! Mail, Google Mail (Gmail), Microsoft Windows Live Hotmail). It’s hard to tell if changing the password would make a difference.
PS, I’m feeling sleepy as I’m typing this, so it would be best if I end here for now.
