It's just my own server for my own mail and receives less than 500 messages per day (most from freebsd-*). The only time it "fails" is when I'm mucking with it. :) In this case it was vinum config and I really screwed it up. > If you choose to do that, you'll need to find someone willing to do the > backup MX hosting for you.

At this time most of my friends can't even figure out how to run their mail client on Windows. > Oh, and setting up postfix on blacksheep as *backup* is probably not > what you want... but I could be wrong.

Actually I think I have this one OK as I can telnet to blacksheep on port 25 and issue mail commands to simulate mail addressed to @mykitchentable.net and it gets forwarded to blacklamb as is should. I should also mention that I've been able to do this on both the 10.2 and 1.2 interfaces. It's just that when I change the NAT entry in my router, I never see any connections initiated to blacksheep. And unfortunately the logging facilities on the 3Com are minimal so I don't know where the failure occurs. Drew
