I have been using Gmail since May 2004. During these almost four years, I didn’t know a very interesting feature of Gmail. I just thought to share with those who may find it new addition to their knowledge.
Google Mail or Gmail allows only one registration for any given username with all capitalization or dot variations, thus all future registrations are made unavailable for any dot variants.
Gmail’s help centre says that Google Mail does not recognize dots as characters with-in usernames, hence adding or removing dots for Gmail address is not going to impact on the destination address; which means, messages sent to [email protected] and [email protected] will reach [email protected]
