Sorry about the misplacement of my post. I was able to tracert and
ping pop3.domainname.com, but I was not able to telnet to it. Telnet
said it was unable to connect to the host on port 25.

Any suggestions?

Hi - I replied in the SBS group.

We have users not on the Exchange server, so I set it up to forward
all messages with unresolved hosts to our hosting company. It was
working fine until our hosting company changed from
mail.domainname.com to pop3.domainname.com.

(We use Exchange with the POP Connector to collect our mail.)

Once this change happened, it will no longer forward offsite. First,
I was getting the below message. Then I changed the forwarding to go
to pop3.domainname.com.

The message we receive is: The destination server for this
recipient could not be found in Domain Name Service (DNS). Please
verify the email address and retry. If that fails, contact your
administrator.

After I made the change to pop3.domainname.com, I get the following
message:

This is an automatically generated Delivery Status Notification.

THIS IS A WARNING MESSAGE ONLY.

YOU DO NOT NEED TO RESEND YOUR MESSAGE.

Delivery to the following recipients has been delayed.


The messages are never delivered. Any thoughts on what I need to
change?

Thanks!

Hi - since you're mentioning "the POP connector" I'm presuming
you're using SBS. Exchange doesn't have a POP connector - note that
any questions related to that config should really be posted in
microsoft.public.windows.server.sbs.

That said - the error you're getting is pretty clear; your server
can't find pop3.domainname.com in DNS. Can you ping that and get an
address in return? Telnet to it on port 25?
