Your email addy here is safe. My guess is you could very possibly have a mal-ware virus/trojan infection farming your account records.
Never open any attachments unless they are verified to have originated from a trusted source....and confirmed to have been sent by them.
Keep well away from warez, porn and file sharing sites and proggies.
Try an online Virus scan to check for existing infection.
Keep a clean system and maintain protections and you'll be fine....
