>>>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.

>>Have you actually checked the headers of the email and the route the email took? Or are you just looking at the to/from address? If the latter they are meaningless and a person can put anything they like in them. You need to check the actual email headers and routing details.

>I did figured (thanks to Google) how to see the header of the message. And it shows the same, wrong - his - email address.

But you say his email address is different by a period? Then its not the same address.
