I'd guess that it's because someone has their mail forwarded somewhere.  I had
the same thing happen, it took a bit of work to nail down which address was
the problem.  Look carefully at the headers, you may find where the address
was relayed from the intended host to the one that's bouncing, then look for
that host in your list.  Once you have a list of 'suspects', send them a test
message that says you're checking for valid addresses, then see what bounces. 
Since you have a couple addresses in the same domain, I'd put them close to
the top of your 'suspect' list.  Good luck!
