The 429 you’re seeing is Stalwart’s JMAP server enforcing its authenticated‑user HTTP rate limit, not a Vandelay bug. By default an authenticated account is capped at 1000 requests per minute (rateLimitAuthenticated), and a bulk export/import of many objects can exceed that quickly. Vandelay is designed to handle this automatically: it backs off and retries per the Retry-After value (as your log shows: “waiting 13s before retry 1/5”), so in most cases it will simply take longer but complete successfully, since imports/exports are convergent and idempotent.

If it keeps failing rather than just slowing down, raise the limit on the target server. This is set on the Http singleton, editable in the WebUI under Settings › Network › HTTP › General (or via the API), e.g.:

{
  "rateLimitAuthenticated": {"count": 5000, "period": "1m"}
}

Increase the count (or period) enough to accommodate the bulk transfer, then run the export again — Vandelay will resume from where it left off rather than restarting.

The suggestion is to run the command as an administrator to bypass the rate limits, not as the mailbox owner.
