Catch-All Not Working - User Doesn't Exist

Hi,
I am trying to setup the catchall email address in CWP but when i send to an address that doesn't have a proper mailbox i get user doesn't exist back, rather than the email being forwarded to the catch-all email address.

Any ideas?


I get back from the server:
