You do not have permission to send to this recipient, external. with all users

Recently a user has reported a problem emailing an external contact they get a NDR back saying :

Your message did not reach some or all of the intended recipients.

      Subject:      QUERY
      Sent:      28/09/2007 10:27

The following recipient(s) could not be reached:

      exampleuser@external..Gov.UK on 28/09/2007 10:27
            You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            <hda02.hf.external.gov.uk #5.7.1>              <- Not ANY of our exchange servers

When I trace the message via Exchange the email is passed out of exchange and onto our hosting email servers (MessageLabs)

"Message Transferred to server-4.tower.messagelabs.com through SMTP'

from further investigating it turns out no one can email this external address they get the same NDR. However I can email the address from my Hotmail account. As the message leaves exchange and passes to our hosting mail servers is this a problem with my end...or the External users ?

Thanks

Just to clarify

           You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            <hda02.hf.external.gov.uk #5.7.1>    <- That is NOT our exchange server

If the message has gone to Message Labs then the problem is not with your server. You have done your bit and the message has been passed on.
The server in the NDR is the one generating the error. Now it could be that Message Labs are passing the messages to the wrong server, possibly using some cached information. Whereas when you send the message from Hotmail it is passed to a different server. Almost certainly the error is not you, it is somewhere inside the UK Government email system.
