In an interesting revelation, vulnerability of an email address due to a missing dot is revealed. According to internet researchers a missing dot, in an e-mail address exposes it to hackers and cyber thieves. By forming web domains containing the normally mis spelt typos, the researchers received the mails that otherwise would have been bounced back instead of being delivered.
