The solution to your question: https://haveibeenpwned.com/

First change the password of your e-mail account!

For safety's sake, change the password of my e-mail account and make sure no stranger recovery options are entered.

While I find it strange that a hacker who has access to your email account does not delete the confirmation emails. Maybe he just has a username or your address and a password that you use with multiple accounts.

I just changed the password to another option to restore I did not notice

If the nochmel happen, then you should check it again and possibly even test your PC for Trojans or the like.

In addition, it is advisable to check on https://haveibeenpwned.com/ times whether your password was leaked somewhere.

At the email not at two others of mine already

Are these emails somehow related to your current email or accounts?
