I'm on it. I'll let Kent report back the results of our findings.

OK...
My queue is now down to 0.
I am writing from my server. Let's hope this goes through. What I need
to do is figure out what caused:
a) the server to eat all the bandwidth of our T1
b) what caused the queue to get so full and take so long to get out.

192.168.1.5 is my MS ncsw2k3 server
I don't think dns is the problem
It looks like I may have been hacked. That would explain my mail
server pegging out the T1 and some domains blocking my emails out. I
believe that it was my mail server b/c the network went back to normal
after unplugging the ethernet to the server. How can I tell if I have
been hacked? What can I do about it?
Does it make sense that some major sites blocking me would cause me
queue to fill up? Should some emails get through? I noticed that an
email to this list is still in the queue. Why did it not go through?
I am now using my gmail account to get through.
Oh, and the queue is now down to 138
Not a good day for me!

OK, moving any FSMO roles won't have anything to do with your problem
then.
The Domain Naming master also doesn't have anything to do with DNS.
It's
the central manager for your own AD domain and nothing on the outside.
I
was concerned if you demoted a DC that you were getting DNS from.
Where is your toaster going for DNS lookups? Do you have a local cache
(DJBDNS, tinydns)? If so, is that pointing to the root servers for
lookups
or are you forwarding lookups to another DNS?

Ok, now I am subscribed in gmail and should be able to email more
efficiently.
DNS warn - I don't think it is that big a deal, and my ISP does my
DNS. I
am sure he is on .com not .org, thus not the same TLD.
The problem at hand is getting these messages in the queue out 213 and
growing. What is preventing the emails from going to the outside world?
What should I check?

What do you mean you changed a DC to backup? Is DNS still on it? Is that
where you are getting dns from? If you removed AD from a DNS DC, then
DNS
will be flakey if it runs at all.
Try random browsing from the toaster and see how well DNS performs.
I mean that I moved the Operations Master roll on my MS w2k server and
moved it to my MS w2k3 server. One of those rolls is Domain naming
master. However, the DNS seems to be fine. I pinged half a dozen
random web sites and they are resolved fine.
