NDR error #5.7.1

I have a question about the following error message.

You do not have permission to send to this recipient.  For
> assistance, contact your system administrator.
>             <XXXXXXXX.com #5.7.1>

The user/users can send and receive to any other address but this particular one.

Background: New 2k domain w/Exchange 2k. All user accounts were recreated and not migrated. Old 5.5 exchange was infested with netsky. 2k Exchange has anti-virus for exchange in place.

Thanks in advance.

It's definately some sort of delivery restriction.  If this came from your Exchange environment it could be on the recipient mailbox or a configuration problem.  If it's on a remote system, it could be a relay configuration issue or some other problem.  Can you please provide more detail?  People tend to blank out domains here but TLDs are public so you might as well post it.  Tell us what domain you are sending from and who if you don't mind.  Maybe even give us the destination email address.

The carolina.rr.com domain is the only address that seems to be giving all users problems and all receive the same error message.

I wouldnt even know where to start with that domain.  It's an absolute mess.  First, check this link and you'll see their mess:

http://www.dnsreport.com/tools/dnsreport.ch?domain=carolina.rr.com

Second, I tested connectivity to most of their MXs and they are VERY slow to respond if at all.  The servers I was able to connect to did take email from saddlebrook@carolina.rr.com, but I'm pretty sure that they have a system problem on the way to that recipient's server.

There is nothing you can do about this other than call the recipient and let them know they have a problem.  That person can then pressure the ISP.
 
You may also want to try a few tests from yahoo or hotmail.  Some may work and some may fail; that's why you want to test more than once.
