The RBL websites point out that they do no blocking, they just maintian a list - how it is used (as a block list) is down to the user, not the maintainer.</pedant> @taustin said:So yeah, these lists can, if they're maintained correctly, be used as a criteria, but shouldn't really be use as the criteria. In other words, while it's useful to use it to assign a heavy weight to scoring incoming messages, it shouldn't be enough in and of itself to block on. That.
