>>Hi,

>>How could Gmail email make a mistake of sending me emails addressed to someone else? His (the other person) email does not have a period in the email address. The rest of the email address is the same. I even called the sender (this is a legitimate organization) to let them know and we were both surprised that in their system the email address was entered correctly. Yet I am getting his emails.

Those are actually different addresses.
I had a problem with one of my gmail accounts - someone else had the exact same email address without a dot in it - victoranderson instead of victor.anderson - anyway the bozo that had the one with no dots was using the account to spam people, but the return address he put in the header had my email address - so the biggest problem was that I was getting 100's if not 1000's of emails a day that were bouncebacks. I finally manged to fix the problem by going to the gmail web interface and blocking the other address.
