This sounds like a DNS error at the sender's end.  Make sure your public DNS settings are up to date, but other than that it sounds like the sender's system administrator will need to check their DNS settings.
The domain "ford.com" is using MessageLabs and it there that the problem arises.

Have you ever used MessageLabs (or hosted Symantec Anti Spam) services - or was your domain ever with either of them?

If so then ask MessageLabs to reove your domain from their cache (they often forget to remove old clients).

If you have not used MessageLabs (or Symantec) then contact the support desk at MessageLabs and ask them to assist.

grahamnonweiler is right, it is issue with MessageLabs, however instead you try contacting them ask Ford tech to contact MessageLabs and fix this.

sorry for the error in typing... the first line suppose to read.... i cant receive mails from a particular domain (ford.com).....

their tech said its our server that is rejecting their (ford) mails.... this only brings more confusion.. we have checked everything from our end and discover everything is ok. using testexchangeconnectivity .com, mxtoolbox.com and other testing tools..
The tech support at Ford is wrong - they are not reading the error message!

MessageLabs is returning the messages as it can not find an IP address to send the messages to (using a DNS lookup on your domain name).

The Ford tech should be able to do a manual DNS lookup for MX records of your domain and immediately understand the problem. If not then they should not be calling themselves a "tech support".

You will have to contact Ford again (and I recommend you also contact MessageLabs) as we have seen this type of problem frequently with MessageLabs.

One small point, it does look like your mail servers are located in Nigeria, and that might present a small problem for MessageLabs. To get around that (and potential other problems you might face based on location) you could set-up a backup (failover) SMTP  gateway service in Europe or USA and publish that in your DNS with a higher MX rank.
