Anyone can make up an address. One thing to do is never use catchall or autoresponders. Also don't post email address in text on your website or out in open. You may have to trash that email address, if it gets bad. Make sure you don't have a virus sending email. Looking at the full headers will tell where it came from 99% of the time.
