No. This means that your 10. series of IPs does not have relaying access.
You need to have 10.1.12.:allow,RELAYCLIENT="" in your tcp rules too to
allow the 10.1.12.* subnet to relay mail.

These are not relayed mails. These mails have come to the system from remote
hosts for local recipients and are now bouncing. These messages are from
spammers with invalid MX pointers. These mails will remain in queue and
eventually bounce to postmaster.
