Solved MAILER-DAEMON notice for email I didnt sent

Specs: Windows XP

I'm receiving a failure notice from MAILER-DAEMON for 2 days now even though I did not send any mails for the past week esp to the recipients I saw in the failure notice. I'm afraid that someone might accessed my account and use it. I already changed my password today hoping that this might help to stop this, but when I open again my yahoo mail, i received another new failure notice about 30 minutes ago... What is this? pls help.

It's a good thing you changed your password. There are two possibilities, either your account got hacked, or someone is sending email and making it look like it's coming from you (spoofing). If someone hacked your account and sent messages, you would see them in your sent folder. If nothing suspicious is there, then someone is spoofing your address, and there is not much you can do about that.

thanks for the reply, Jowah. Yes, I had change my password yesterday but when I open my computer and went to my yahoo account in the afternoon, I see again another failure message and also this morning, another failure message. I also check the sent folder, i did not see unusual thing that's been sent. I don't understand what is spoofing and what can it do to me and my account?

✔ Best Answer

Spammers use spoofing to avoid huge amounts of bounce messages and prevent themselves from being blacklisted. They basically send out spam, and alter the headers of the email to make it look like it came from another address. In this case, your address. There isn't anything bad that can happen directly to your account, but you might get blacklisted, and if that happens, your legitimate sent emails might end up in the junk folders of your recipients. How they got your address is anybody's guess, but I would say that if it doesn't stop in the near future, it might be time to get another account. If you do that I suggest gmail.
