Hello Shady.C'
Hi, I'm Karl and will be happy to help you today.
What you are describing is your email address as having been hacked and smee is trying to log into your account. Unfortunately, there is no way to prevent anyone from logging into your account.
I have an article describing how email addresses get harvested with an additional step you can take to protect your account from these logins
