Could it be that the Address that is saved in the address book have a error you didn't notice?

I see the Address in your post is InCorrect.. it has a Space in it..


The Header info is saying that it is having 'Host Name Lookp Failures'

There is a problem with the addressing...

I could not get to resolve.

Both and resolve.

The domain is registered but not assigned to a host. It does have a mail exchanger at IP= The primary/secondary DNS is When the primary DNS is queried it reports a primary/secondary DNS of, and the 89 host does not answer a query. Also, I noticed the IP resolves differently or not at all when queried against my local Name Servers. I would suspect there are DNS config problems with the domain name. I would say the problem is on the China end and get the recipient to lodge a complaint with his IT person and/or obtain a free US mail address to work with.
