No, don't pass 'selected' to options.

Either do this:
    $form->default_values( { EmailDL => \@default_values } );
or this:
    $field->default( \@default_values );

This will ensure the default values are selected when the form is
first displayed, but not if the form's displayed again after an
invalid submission.
