title: Should I remove all dots before the @ sign in emails
body: <p>In a web based+REST api system, I want people to enter their email address along a password they choose to authenticate to my service (pretty common practice, nothing new),   </p>
  
  <p>My question is, is it ok if I lower case them and remove any dot (.) before the @ sign?   </p>
  
  <p>To make it even more clear, "ali@example.com" and "a.li@ExamPle.Com" will be the same user.<br>
  So part of this question will be, are there email services out there that are sensitive to dots in your email and you will not receive your email if they are send to the dot less version? Gmail ignores the dots as far as I know.   </p>
