Deploy and Host dmarc-analyzer.net on Railway

DMARC Analyzer is an open-source, self-hosted DMARC monitoring platform for agencies and IT teams managing email authentication across many client domains. It ingests the aggregate reports mailbox providers send under rua=, parses them, and shows who's sending as your domain, SPF/DKIM alignment, and enforcement progress — unlimited domains, no per-domain pricing.

About Hosting dmarc-analyzer.net

Hosting DMARC Analyzer means running two pieces: the application (API and worker, shipped as a single container image that can run both roles in one process or split them across services) and a PostgreSQL database. The worker polls an IMAP mailbox on a schedule, extracts and parses DMARC XML reports out of compressed attachments, and stores the results; the API serves the console and dashboards. Mailbox credentials are encrypted at rest with a key you provide. A single service plus a database is enough for most agencies — splitting the API and worker apart is optional and only needed at higher ingestion volume.

Common Use Cases

Agencies monitoring DMARC/SPF/DKIM compliance across many client domains from one console
IT and security teams moving a domain from monitor-only (p=none) to enforcement (p=quarantine/p=reject) with visibility into what would break along the way
Self-hosters who want DMARC report data to stay on their own infrastructure instead of a third-party SaaS

Dependencies for dmarc-analyzer.net Hosting

PostgreSQL database (provisioned automatically by this template)
An IMAP mailbox that receives your domain's rua= DMARC aggregate reports
A generated encryption key (Security__CredentialEncryptionKey) to protect stored mailbox credentials

Deployment Dependencies

Implementation Details

The app reads its database connection from DATABASE_URL (a postgres:// URI — this template wires it to the Postgres plugin automatically) or ConnectionStrings__Default (Npgsql's ADO.NET format), whichever is set. APP_MODE=all runs the API and the ingestion worker in a single process, the simplest way to run this template. Database__MigrateOnStartup=true applies pending schema migrations automatically on boot.
