  • Thanks for your reply but this regex is taking spaces in local part. Also working for special characters like (,),<,> and many other conditions I don't want.. – Love Sharma Sep 20 '17 at 06:45
  • @Ivar As per my rules I don't think there is regex in question you provided. – Love Sharma Sep 20 '17 at 15:07
