Fluent mail library for NodeJS

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 8617 Authenticated Received Chain (ARC) — header parsing, chain extraction, and signature verification + sealing. ARC extends DKIM/SPF/DMARC across forwarders by chaining per-hop authentication results inside cryptographically-sealed header sets. v3 cuts RSA crypto over to aws-lc-rs via mailrs-dkim 3.0 for ~3× faster sign.

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.

Mailbox metadata storage abstraction for Rust IMAP/JMAP servers: MailboxStore trait + PostgreSQL reference impl + in-memory test fixture. CONDSTORE, threading, flag ops, change tracking.

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.

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.

Outbound mail queue primitives: DKIM signing, DSN generation, MTA-STS lookup, retry/backoff, with a pluggable store trait and a Postgres reference implementation.

Group-commit delivery executor on top of mailrs-maildir 1.2's deliver_batch. Accumulates per-path delivery requests from concurrent async tasks (SMTP / LMTP / IMAP APPEND sessions) and flushes each path's batch via a single fsync, with optional pipelined in-flight flushes (max_concurrent_flushes=2 default) to hide disk wait behind batch collection. Caller awaits a oneshot::Receiver for per-message confirmation. Default tuning: max_batch=64, max_wait=10ms, max_concurrent_flushes=2.

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.

IMAP wire-format helpers (RFC 9051): FLAGS / INTERNALDATE / quoted string / address structures / BODY[…] section extraction / BODYSTRUCTURE assembly. Pairs with mailrs-imap-proto (parsing + state machine) and mailrs-imap-codec (line + literal framing). 22 standalone pure functions, no I/O.

RFC 5322 / 2046 / 2047 / 2231 outbound mail builder. Constructs canonically-compliant raw bytes for plain-text, multipart/alternative, and multipart/mixed messages — encoded-word headers, soft-fold lines, CTE selection (7bit / quoted-printable / base64), boundary collision-scan. The inverse of mailrs-rfc5322 + mailrs-rfc2047 + mailrs-mime parse stones.

RFC 5545 (iCalendar) parser, serializer, and iTIP semantics — zero I/O, hand-rolled, with VTIMEZONE + RRULE support.
