I do it based on the $authenticated_id. All users who authenticate,
must use "their own domain" (which is selected by an MySQL lookup).

So my snippet looks like this (placed in acl_check_rcpt )

deny    authenticated  = *
      set acl_m9 = ${lookup mysql{select domain from mail where
         username = '${quote_mysql:$authenticated_id}'} {$value} fail}
      senders        = ! $acl_m9
      message        = Sender domain is not $acl_m9
