Is it that there are two many periods? You're only allowing hyphens in the first part of the address after the @ symbol, though, before the first period. Maybe your regex should be: @([a-zA-Z0-9-]+\.)+[a-zA-Z.] Just noticed that your period is not escaped, either, so you're actually matching any character with the one that's outside of the [ and ] character classes. ---John Holmes...
