Hi there,
i have zcs-5.0.0_RC1_1538.UBUNTU6.20071002173103. I have two mailservers in split domain setup with zimbra as primary mail system. Mail delivering for local mailboxes or for mailboxes on secondary system worked well until now. But i don't know why.

If i try to send email for local mailbox, zimbra send email to secondary mailsystem.

If i try to send email for local-only mailbox, zimbra loop.

Is this some known bug in RC1? I can't find it in bugzilla.
