Comment (by farhadvn):

 i used a function for this problem! Of course, it may not be up to
 WordPress standards, but I hope it helps

 {{{
 function useremailcheck($approved){
  // example function
 $email = filter_var($_POST["email"],FILTER_SANITIZE_EMAIL) ?: null;
 // this SANITIZE is after wordpress validation, so this filter is not make
 sense, however wordpress devs can delete or replace it with a standard
 wordpress var.
 if(is_user_logged_in() === false
 // check if 1. user is not loggedin
  && isset($email)
  // 2. email is set
 && get_user_by("email",$email) !== false
 // 3. we have an user with this email
 && $approved != "spam"
 // 4. not marked as spam before
 ){
  $approved = 0;
 // Force pending even if comments are open to all
  }
   return $approved;
 }

 add_action("pre_comment_approved","useremailcheck",999);
 }}}
