I've recently taken over this account which apparently has had several
"experts" over the last 10 years.  The customer at one time had sbs 4.5 with
a server name of server and an internal domain name of company, not
company.local, just company.  For purposes of discussion, let's say their
public domain was company.com.  They upgraded to SBS2000 in 2003.

Now in Exchange, there are two servers listed, one called server and we'll
call the other newserver.  I cannot access server, when I click on it, I get
a time out.  I can click on and configure newserver.  However, I discovered
that server was setup as the master and I have changed that with newserver as
the master and server as a member.  I have been unable to delete the old
server.

When I send mail, I get the normal SMTP connector.  However I'm also getting
a strange remote mail listing under queues.  The queue name is server.domain
(which is the old server name) and when I click on that, I get the sent from:
newserver-IS@company.com.  There are several of these messages queued up and
if I delete them, more appear.  I don't know who they are going to and I
can't read the message.

My questions are:
Is there any way to read the messages in queue so I can figure out what they
are?
What is the origin of messages with the from being newserver-IS?  What does
the IS mean.
How can I delete the non-functioning listing of the old server in Exchange
2000.

y'all have been great.  Thanks for your help.
