Test email to new account failing

[AmozHouse]

Scenario: We have our own website and email hosted on our main server and have just started using it for our own smtp; we also host client websites and email on the same server and have some email accounts on a separate server, which are due to be moved over to the main server.

Post changing to use our main server for smtp, I set up two new email accounts for a client, e.g [email protected], these are on the second server. I then sent a test email to [email protected] from outlook using [email protected] and got the following in the maillog

Client Jun 11 15:01:01 centos postfix/smtpd[32576]: NOQUEUE: reject: RCPT from host-2-103-23-143.as13285.net[2.103.23.143]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<AmozLaptop>

If I send an email to the [email protected] from my hotmail account, the email arrives on the old server.

Does this mean for every existing email customer account on the old server and all new accounts, I need to manually add their address to the virtual mailbox table on the main server? And if the answer is yes, how do I do it?

Thanks

Tried this...

/usr/local/psa/bin/domain -u clientsdomain.com -mail_service false

... didn't cure it
