Resolved Question: I am getting Spam in my Inbox folder how do I make it stop?

For the past month or so, I am getting spam in my Inbox folder and the address is the same except for the 2nd part. Here is an example of the email address that keeps spamming me. MAILER-DAEMON@n16.bullet.mail.mud.yahoo.com. The part that differs are the n16. Each email has a different n#. How do I make it stop?
I don’t send emails I hardly ever send emails. It is very rare that I do send emails.
