 As a side effect of this ingress mode "feature", make sure that the ingress subnet is not in your RELAYHOST, otherwise you would create an smtp open relay :-(

+When using ingress mode you probably want to disable rate limits, because all requests originate from the same ip address. Otherwise automatic login attempts can easily DoS the legitimate users.
