I've found the below regular expression in another answer to check the email input field and I would like to know how can I set the minimum amount of characters before and after the @, and also at the end, because this accept 2 characters after the dot, example .co, but I would like to know how can I set this to 3 only too.

 /^(([^<>()[\]\.,;:\s@\"]+(\.[^<>()[\]\.,;:\s@\"]+)*)|(\".+\"))@(([^<>()[\]\.,;:\s@\"]+\.)+[^<>()[\]\.,;:\s@\"]{2,})$/i;

Thanks in advance, Leandro.
