What do you mean all your other emails are working fine?  You can send email to everyone else but that single domain?  

Yes. this domain is doing this. But I have over 50 clients here sending email all day and I only got this problem with this domain. this is the email address.

-----------------------------------------

I just sent an email. to the address with my hotmail and got the same problem. So i know for sure it an't us and IM gonna stop this question

Maybe you were getting spammed.  Megamailservers.com is a web-based email though.  At least you know your side is ok.

That NDR is originating from your Exchange server, so it could be a problem on your end.  Please see http://support.microsoft.com/kb/895857 for details on troubleshooting.

?????? explaine please

That domain comes back with a "Reverse DNS Lookup Failure"
http://www.mxtoolbox.com/diagnostic.aspx?HOST=mail.wroughtfurniture.com

Most larger mail services won't deliver to a mail server that doesn't provide Reverse DNS info.  If your Exchange server is configured to relay through MegaMailServers.com then they are probably not allowing the connection to the domain in the same way that GMail doesn't allow it.

They have an alternate email address on their website of fzhuge@126.com... I'd try that instead.

Yeah but I have tested this with hotmail and gmail and my work email and all fail. how could this be on my end at all?

Your server is fine though, its the guys on the other end that are screwed up.
