Absolute Control Over
Email Authentication.
Don't just monitor DMARC. Enforce it. InboxPin provides the deep infrastructure visibility required to achieve `p=reject`, flatten SPF records, monitor MTA-STS, and deploy BIMI across complex enterprise architectures.
| Source IP / Host | Organization | Volume | SPF Auth | DKIM Auth | DMARC |
|---|---|---|---|---|---|
| 209.85.220.69 mail-sor-f69.google.com | Google LLC | 1.2M | Pass (Align) | Pass (Align) | Pass |
| 198.2.132.14 mta14.mailchimp.com | Mailchimp | 450K | Fail (Misalign) | Pass (Align) | Pass |
| 45.133.22.11 unknown.host.net | Unknown | 12K | Fail | Fail | Reject |
Beyond Basic DMARC
Achieving p=reject is just the beginning. Secure your entire email pipeline with our advanced authentication and infrastructure protocols.
Aggregate (RUA) Intelligence
Ingest millions of XML reports daily. We parse, enrich, and visualize your RUA data to identify every IP sending on your behalf, mapping them to known ESPs and infrastructure providers.
Forensic (RUF) Threat Analysis
Deep-dive into DMARC failures. Receive redacted email headers and routing paths for messages that fail authentication to identify exact spoofing vectors and configuration errors.
Dynamic SPF Flattening
Bypass the 10 DNS lookup limit. Our dynamic SPF flattening service automatically resolves and flattens your nested includes into raw IP blocks, keeping you perfectly compliant.
DKIM Selector Monitoring
Track all active and deprecated DKIM keys across your ecosystem. Detect unauthorized key usage, track key rotation schedules, and monitor cryptographic strength (1024 vs 2048-bit).
Hosted MTA-STS & TLS-RPT
Enforce strict transport layer security. We host your MTA-STS policies and ingest TLS-RPT reports to ensure connection-level encryption between MTAs is never compromised.
BIMI Readiness & Hosting
Boost brand trust by displaying your logo in the inbox. We validate your SVG formatting, host your BIMI assertion records, and track VMC (Verified Mark Certificate) status.
Forensic-level insight into every failure.
Raw XML reports are impossible to scale. InboxPin ingests, sanitizes, and categorizes millions of RUA and RUF reports daily. We automatically classify sending sources into Known Providers (e.g., Salesforce, SendGrid) and Threat Actors.
Infrastructure Mapping
Automatically identify undocumented shadow IT sending on behalf of your domain before enforcing strict policies.
Cryptographic Alignment
Track strict vs relaxed alignment rules for both SPF (Return-Path) and DKIM (From domain) signatures.
Threat Intelligence Feeds
Cross-reference failing IPs against global blacklists to instantly classify malicious spoofing attempts.
Track unauthorized traffic by geography.
Spoofing campaigns often originate from specific regions or bulletproof hosting providers. InboxPin maps every failing IP address to its origin country, ASN, and hosting provider to give you macro-level visibility into coordinated attacks against your brand.
