Just in case an actual human reads this blog, here is a quick thing I would like to share with everyone.
This site allows you to check if your email has been compromised in a previous breach or hack of some company. You can set up alerts for any domain you manage as well.
I would also like to show another feature on his site that you can use:
https://haveibeenpwned.com/Passwords
This allows you to check if your password has been "leaked" or part of any previous breach.
