As I said, I guess that your production MTA is properly configured in the DNS. Therefore sendmail running on your production mailbox server knows where to deliver the mail for your domain. Test/Acceptance systems are usually not setup for external access and thus not published in the DNS. Sendmail running on the other mailbox server can most likely not find the MTA, or just thinks it should try to deliver the mail locally.
Use my earlier suggestion and modify the webmail MTA and MTA for outgoing mail in the Zimbra Admin interface.
