domain_settings_form_alter(&$form, $form_state, $form_id)

Implement hook_form_alter()

This function checks the #submit value of the form to see if system_settings_form() has been invoked. If so, we may attach domain-specific settings to the form, if the user is permitted to use this module and the form is not on the administrator's denied list.
