You can try using this Regex:

/^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/

@dnyaneshwarsuryawanshi You mean to say hypens, underscores and periods should be allowed if they are not the first character, right? – Miral Kumbhani Sep 10 '19 at 06:23
only letters (a-z), hyphen(-), underscore(_), number, and periods for email address allowed. – Dnyaneshwar Suryawanshi Sep 10 '19 at 11:52
