Are you receiving spam emails from your own email address Or is it something else you are pointing at?
If you are receiving emails from your own address, it is called "spoofing". The emails are sent to various address and your email address is mentioned in the return-path which then delivers emails to your email address once it bounces back.
The only way to resolve the issue is enable SpamAssassin and configure "Account Level Filtering" as per the Subject, Email Headers, Contents etc which will then reject these emails.
