In that case, SMTP mail to non-existent recipients in virtual mailbox
domains will be rejected.

For local submission, virtual_mailbox_maps is not checked until
the mail gets to the delivery agent. Only virtual alias domains
have recipient validation done by the queue manager (via
trivial-rewrite).
If local mail is sent to non-existent users, you'll need to configure
dovecot (or other delivery agent) to know which users are valid.
Alternatively, make the domain a virtual alias domain, and rewrite
all valid users to some other domain actually used for delivery.
