Receiving someone else's email to my address?

Question

I still keep on receiving someone else's emails using my email address which is the same. How could two people have the same address? If yahoo keeps on saying that it's impossible or that they wrongly wrote their email address, etc, that it totally not right. I keep getting their paypal emails, their ebills etc., which means that yahoo is totally unsecure. And if our address is given to someone else after a year, that is also not right. I have had this address since 95 and never closed it. As far as I can see, there are several people with the same email address. Indonesia, Philippines, Mexico, and the US. Doesn't matter if IPs are different, I am still getting their emails.  

As the result however, I am not using my yahoo for anything important. Denying that this is a problem or that it is even impossible, does not solve the problem. It is a major security problem.
