That isn't necessarily a good test; for example, we've got a couple of servers in a cluster. One IP pointed at the cluster is mail.hiwaay.net, and that is what is used in HELO/EHLO when making outbound connections, but the connections don't come from that IP. They come from the cluster member's IP so that when we get a complaint with sending IP, we don't have to look through the logs for the whole cluster to find the offender. -- Chris Adams <[email protected]> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
