Please do not use a pattern for email validation. Every regular expression for email validation is missing something. Lots of people gone through a process with the conclusion, that it is nearly impossible to get a perfect validation. The good part about is, we can leave this to our browser developers. They got it quite right and we should use their standard for email validation now.
