I forgot to add the other part. The reason I use @www2.aaos.org and md.aaos.org is that the Imail server that holds these doamins performs a different function than my corporate server. It is mainly used as a list serve and as a forwarding address for people who want @md.aaos.org e-mail addresses to be forwarded to their own e-mail address.
The second part is kind of a long story. We have 2 T-1 circuits comeing into our building. They are from separate providers, Winstar and Focal. We have implemented a device from Radware canlled a linkproof that will load balance incoming and outgoing traffic. The way it load balances incoming traffice is by having our authoritative DNS (Winstar) create NS records that forward any requests to the LinkProof, who in turn hands out 2 A records. One for the Winstar circuit and one for the Focal Ciruit. This the reason that the dnsstuff.com report said my DNS server is down. It's not down, it just doesn't respond the same way a DNS server would expect. I hope this makes sense. Thanks for all your help Tom -----Original Message----- From: R.

The first question is why are you using @www2.aaos.org instead of @aaos.org? That is rather odd -- unless you have a reason to do so, I would not recommend doing so. It will just cause confusion. The problem is that your DNS servers are seriously broken: http://www.dnsstuff.com/tools/lookup.ch?name=www2.aaos.org&type=MX shows that your DNS servers are timing out for the MX record lookup for www2.aaos.org, but http://www.dnsstuff.com/tools/lookup.ch?name=www2.aaos.org&type=A shows that they are responding with A records (but with 0-second TTLs!!!). That's very, very weird. Technically, a mailserver should be able to send mail to @www2.aaos.org, assuming that you've done other stuff correctly (it should send to the A record if the MX record doesn't exist). But since your DNS server isn't responding, a smart mailserver will "know" that it is down/unreachable, and "know" that the A record doesn't exist, either. So the real issue is that your DNS servers aren't returning the MX record for www2.aaos.org. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers.
