When a user clicks "Report Spam" in their email client, participating mailbox providers transmit an Abuse Reporting Format (ARF) message back to the sender via a Feedback Loop (FBL). Automating instant removal is critical.
1. Automated ARF Parser Architecture
| Step | System Action | Processing Latency | Output |
|---|---|---|---|
| 1. Ingestion | MTA receives ARF message at fbl@mailcampaign.us | < 500ms | Raw MIME Multipart Message |
| 2. Parsing | Extracts original Message-ID and recipient address | < 50ms | Structured JSON Payload |
| 3. Suppression | Adds address to Global Suppression Database | < 10ms | Hard opt-out flag activated |
