If the X-Originating-IP header is enabled, zimbra marks injected/local messages as spam.

X-Spam-Flag: YES

Additional Content

The Spamhaus PBL is a DNSBL database of end-user IP address ranges which should not be delivering unauthenticated SMTP email to any Internet mail server, except those provided for specifically by an ISP for that customer's use. RCVD_IN_PBL lists IP addresses that are not expected to host a normal mail server, and the PBL has Self-Service removal and IP owner management mechanisms.

  • IP Address Self-Service Removal Mechanism

A feature of the PBL is the elimination of 'false positives' with a server-identifying and automatic removal mechanism for single IP addresses. This allows end users with static IP addresses within a larger dynamic pool, and legitimate mail server operators, to assert that in their opinion their IP addresses are a trustworthy source of email and to automatically remove (suppress) their IP addresses from the PBL database.
