Dear Richard,
"Host unreachable" may mean that the other company's e-mail server
is down.
"network error during host resolution" may mean that your Exchange
Server does not recognize the e-mail domain.
In the Exchange Admin program, on the IMC, on the Connections tab,
Message Delivery is set to "use DNS". If this is correct, and there is no
Internal MX Record for this particular e-mail domain (and there should not
be), then you are at the mercy of your ISP's DNS.
In this case, when you run "nslookup", you ought to change your
default Server. When you run "nslookup", it uses information from your
Internal DNS Server and then from your ISP's DNS Server. Somebody else's
DNS Server may contain an MX Record for the e-mail domain your are
attempting to send to. Then, contact your company's ISP, and inform them
that a particular MX Record has not been propagated to their DNS Server.
Let them see if there is something that they can do.
For about a month and a half, I was unable to send posts to this
list, because Wawa changed ISPs, and the new ISP had no idea (no MX Record)
who "@ls.swynk.com" was.
Oddly enough, no one from the list even noticed that I was not
posting or replying.
Go figure.

Start, Run, CMD, NSLookup, Set Type=MX, type in the domain name and see
what you get.

Yes the outbound messages are the ones that seem to get stuck. I looked
at details of the messages and most of them said (host unreachable) but
there were two other ones that said (network error during host
resolution). Im not sure what that means but I think its on their side.
(hopefully) Also if you can let me know how to do a MX Record lookup.
Is this just looking up a web site or do I do it through my dns. I
thank you for your response and appreciate it so much.
Thank you

Richard, THERE IS NO NEED TO YELL. You haven't said with it is the
inbound or outbound queue. I will assume outbound since it would be
rare for inbound messages to be stuck. If you are not relaying to
another server it is very common to have messages stuck in the outbound
delivery queue. If you click on the Details button it will tell you why
the message has not been delivered. The most common reason will be Host
Unavailable or Host Undeliverable. That means that for any number of
reasons your server could not initiate a TCP session with the recipients
mailhost. If most of your messages are going through then there is a
probably nothing wrong. Especially if the messages in question go after
awhile. You can test a connection by doing an MX record lookup for the
host in question and then initiate a telnet session to port 25 to that
host from your Exchange server. If that fails, then your IMS will be
unable to send the message.
Scott.
