If spam is being sent out from your email account, your email address has either spoofed or hijacked.
Spoofing an email address is when an email is sent out with your From address, even though they have no access to your account. There’s really no solution to spoofing. Fortunately, hijackers tend to change spoofed addresses frequently and the annoyance will disappear soon.
Hijacking is when someone has taken control of your email account. They can read your mail and target people you know with spam; even lock you out of your own email account.
As soon as you discover that your email address is spamming, immediately try to change your email password. But if you're unable to change your password, it means the hijacker has changed the password and now controls your email account. Contact Us if you are unable to change your email password.
