An RFC 7489-compliant DMARC aggregate report parser

Simple library to parse email DMARC reports

RFC 8460 SMTP TLS Reporting (TLSRPT) — _smtp._tls TXT record parser, RFC 8460 §4 JSON report data model, FailureType enum (14 result-type values from §4.3), and a builder that takes per-connection event facts and produces an owned daily report ready to serialize + sign + submit. Pure: no SMTP / HTTPS / gzip in-crate. Pairs with mailrs-mta-sts.

Composable SMTP receive pipeline framework — Stage trait + early-reject executor + pure decision logic + RFC 8601 Authentication-Results helpers. Framework-only; bring your own greylist / DKIM / virus-scan / scoring stages.

RFC 8461 MTA Strict Transport Security (MTA-STS) — policy + STS record parsers, MX pattern matching, enforce(policy, mx) decision, plus a Cache trait + in-memory reference impl. Pure: no HTTP / DNS — bring your own resolver and HTTPS client and feed the parsed bytes in.

RFC 2045/2046 MIME body parser. Walks the multipart tree, decodes Content-Transfer-Encoding (base64, quoted-printable, 7bit, 8bit, binary), exposes text/HTML extraction + find-by-content-type + attachment iteration. Layered on mailrs-rfc5322 (headers) + mailrs-rfc2231 (parameters) + mailrs-rfc2047 (encoded-words).

RFC 6376 DKIM signature verifier + signer. Parses DKIM-Signature headers, applies simple/relaxed canonicalization, verifies rsa-sha256 / ed25519-sha256 against the selector TXT record. RSA primitive backed by aws-lc-rs for ~3× faster sign vs pure-Rust. Pluggable DNS via DkimResolver trait.

Concurrent URL status checker that captures comprehensive metadata in SQLite.

RFC 7208 Sender Policy Framework verifier. Pure-Rust evaluator with a pluggable DNS resolver trait; ships an optional hickory-resolver-backed implementation. Bounded DNS-lookup limits + loop detection per spec.

Outbound SMTP client: MX resolution, DANE/STARTTLS, response parsing — async, transport-agnostic primitives for RFC 5321 senders.

Configuration management for RusMES — TOML/YAML auto-detection, 30+ environment variable overrides, validation, and SIGHUP hot-reload

SMTP for AI agents. No middleman. Self-hosted mail server (AI Mail Exchange) with built-in MCP.
