Hi everyone,

I'm new here, and this is my 1st post. I'm so frustrated that I've found my way here to get somehelp from the Guru's here.

My company uses msoft Exchange 2000 installed on a Server 2003 machine. While our clients are using Vista with outlook 2007.

recently We installed a new NPC, and ever since users have been getting an error below :

Could not be delivered because the domain name was unresolvable:

Unable to resolve route mbfcards.com (MX) - *

The following recipients were affected:
<username>@mbfcards.com



This is a peculiar error, because the users use their contactlist to fill up the address field (the user field is populated by names instead of full email address)and send out as a normal practice, but somehow this error occurs and our mail marshall rejects the email immediately. however if I or the user were to type in the whole address field, together with the domain name and ".com" etc2.. it could go through.

Why is this happening?? And its happening randomly.

Sorry, I'm not familiar with that term/product.  What is it exactly?  Did this issue only appear after the installation?
