I put together a crappy site for my dad's business...let's call it "example.com" for examples sake. On the site my dad's email is listed. It's completely different from example.com. Somehow I'm getting a ton of junk emails like this with my dad's website in the address, for example: MAILER-DAEMON@heapmail.com.pl and Delivery status notification (failure) It seems junk mail is being sent to addresses like: jonsmith@example.com, tim@example.com, mary@example.com and is getting kicked back. Why would these names have my dad's "example.com" on them and why are they coming to me? I get hundreds of these on some days and it's causing me to reach my email storage limits.
