I am running exchange server 2003 SP2.  When we try to send a message to one particular domain we get the following error.  I tried sending a message to the email address from my gmail and did not get a return.  Why would this only be a problem from our corporate mail senders?

The following recipient(s) could not be reached:

      name@domain.com on 4/4/2007 8:02 AM
            No route was found for the recipient server.  Please contact your system administrator.
            <server.domain.com #5.4.4>

The error means what it says - your server cannot find a route to the domain.
That will often mean the problem is with your ISP.

You can confirm that by seeing if you can telnet or tracert to the host listed in the domain's MX records. Lookup the mx records in nslookup on the server...

For example... microsoft.com:

C:\>nslookup
Default Server:  server.domain.co.uk
Address:  192.168.1.1

> set type=mx
> microsoft.com
Server:  server.domain.co.uk
Address:  192.168.1.1

Non-authoritative answer:

microsoft.com   MX preference = 10, mail exchanger = mailc.microsoft.com
microsoft.com   MX preference = 10, mail exchanger = maila.microsoft.com
microsoft.com   MX preference = 10, mail exchanger = mailb.microsoft.com

maila.microsoft.com     internet address = 131.107.1.7
maila.microsoft.com     internet address = 131.107.1.6
mailb.microsoft.com     internet address = 131.107.3.123
mailb.microsoft.com     internet address = 205.248.102.77
mailc.microsoft.com     internet address = 205.248.102.78
mailc.microsoft.com     internet address = 205.248.102.79
>

When you have the MX server information, see if you can telnet to port 25 of the remote server.

For example (using the above information)
telnet maila.microsoft.com 25

If you get the route issue, do a tracert, so using the above example

tracert maila.microsoft.com

If there is a route issue the traffic will die at some point - when you will need to speak to your ISP.

If all domains fail then the traffic is being blocked.

I have seen that caused by antivirus before, but it could also be your firewall or your ISP. As you are trying to troubleshoot a single provider, I doubt the last two, so I would suspect that something is stopping you from using telnet - McAfee Enterprise and some versions of Symantec have that "protection".
