Maybe someone's just running accounts through a script with generic passwords to see if anyone has sci enabled.
I have receieved some sort of mail before and you must not clicked those links. Anyway you try to checked your e-gold account and if its working fine then there is no need to worry.
Is there a link in the email telling you to access your account? If there is it's a phishing email. If it's legit you can strengthen your password both for the e-gold and the email wher you send the PIN.
