User unknown in virtual mailbox table

Hi Im setting up a new user. Internal emails are working fine but sending an external email bounces with "

Diagnostic-code: smtp;550 5.1.1 <xxxx>: Recipient address

rejected: User unknown in virtual mailbox table"

Any thoughts?

OS X Yosemite (10.10.3), OSX Server - 10.10.3
