Build an Email Agent That Triages Bounces Before It Retries

Описание и применение

Агент корректно обрабатывает уведомления о доставке, предотвращая повторные попытки и защищая репутацию отправителя.

Задача

Agents may incorrectly treat delivery status notifications (DSNs) as customer replies or retry bad addresses, harming reputation.

Результат

Agents correctly triage bounces, preventing unnecessary retries and protecting sending reputation.

Рабочий процесс

• Pull raw DSN from agent inbox via CLI
• Fetch message details and raw EML
• Parse multipart/report to extract message/delivery-status
• Normalize recipient and correlate Original-Message-ID
• Determine failure type (hard, soft, unknown)
• Apply action: suppress, retry with budget, or quarantine

Доказательства

A naive agent treats this as a customer reply. It drafts an apology to the daemon, or it retries the same bad address on every poll.

Hard, soft, and unknown failures need different actions.
