It works now, thanks so much. I understand much more clearly how this all goes together. I was rejecting non-fqdn hostnames before I was giving it the opportunity to override the restriction according to the data flow. I'm really excited and inspired by what I've been able to do with everyone's help. I hope to upgrade the server before the end of the year. It's been running fine the way it is. We haven't really had the resources to spend on something that's working just fine. The server is on the other side of the country, and it just routes mail all day and doesn't complain. It had nearly 700 days of uptime before I rebooted it recently, without incident. Thanks again, Alex
