| Yes this is very frustrating.
| 
| The details are not so hard to guess.  Unless this post is different,
| anyone can send an email to a nonexistent user at a google service and
| they accept it and bounce back to the envelope recipient. *sigh*.

| 
| This is doing very much harm.
| 
| I would even go as far as to say that Google is making a business case for
| its latest purchase, postini, in a very evil way, every second this proble
| goes unsolved.
