First stable release of MailFerry — High-Performance Native IMAP Migration
Engine.

Added

  • Native asyncio IMAP protocol core: pipelined commands, streamed message bodies
    (constant memory), non-synchronising literals (LITERAL+), wire
    compression (COMPRESS=DEFLATE), STARTTLS and implicit TLS with
    certificate verification on by default, inactivity and byte-progress
    watchdogs, capability-driven optimisation with --baseline fallback.
  • Migration, sync and backup in one command: fresh migration, fingerprint
    adoption of destinations pre-synced by other tools (duplicate-free,
    even after State Database loss), and incremental top-up runs; deletions
    are never propagated; optional --sync-flags re-applies flag changes.
  • Per-message State Database (SQLite WAL): planned/inflight/done/skipped
    states, source→destination UID mapping via APPENDUID, UIDVALIDITY-aware
    re-verification, crash-window reconciliation, mailbox leases,
    import-state migration from the legacy wrapper, compact maintenance
    command.
  • Scheduler: worker pools, per-host connection budgets, parallel folder
    pipelines inside large mailboxes, throttle-aware backoff; authentication
    failures are never auto-retried.
  • Folder planner: NAMESPACE/delimiter translation, special-use role mapping
    (localisation-proof), Gmail virtual-folder policy, mUTF-7 Unicode names,
    include/exclude globs, explicit --map file.
  • Live Dashboard: alternate-screen differential renderer, two-line MailFerry
    banner, global progress (messages/data %, throughput, ETA, duplicates
    prevented, reconnects, retries), per-mailbox operation verbs and detailed
    Source Server / Destination Server panels; non-TTY status lines;
    --json-progress snapshots.
  • Reporting: session log, per-mailbox logs, results.csv, end-of-run
    summary, optional NDJSON event logs, --trace protocol logging with
    credential redaction.
  • CLI: run, check (write-nothing preflight), init, import-state,
    capabilities, verify, compact; --version, --about, --help;
    exit codes 0/1/130/141.
  • Tooling: single-source version and identity (mailferry/__init__.py),
    release builder with branding/header/changelog/license validation and
    SHA-256 checksums, AGPL source-header applier, end-to-end fake-IMAP test
    suite (34 checks).
  • Packaging: standalone mailferry.pyz (zipapp), source archive, wheel.
