*) Both Postfix and Dovecot will lookup mail addresses against LDAP/SQL server for local delivery.

"SPAM FROM LOCAL" notices which should get delivered to root@<mydomain> are being bounced by postfix.
Please show us full bounce message and/or related log in Postfix log file, we need them for troubleshooting.
I guess what you need is root@<your_server_hostname>, not root@<your_virtual_mail_domain_name>.
