 > @tsimmons, Have not reviewed all this bug, but looks like you would be
 sending a lot of mail to `wordpress at co.uk`. Does WP use something like the
 public suffix list? https://publicsuffix.org/

 I don't think so, and probably really shouldn't. It really should just be
 a configurable option (from address for admin messages) which the plugin
 provides. Automatically deriving from user supplied input DIRECTLY is bad,
 though, as the present code does.
