Checkpoint 005 — SMTP Egress

Ngày: 2026-04-24
Trạng thái: ✅ Hoàn thành
Verify: go build ./... thành công

Việc đã làm

SMTP Sender (`internal/mail/smtp.go`)

Gửi reply email (requirements 4.3):

Subject: thêm prefix Re: nếu chưa có
Body: task.AIResponse từ OpenClaw callback
Threading headers:
- In-Reply-To: <original message_id>
- References: <original message_id>
MIME: text/plain; charset=UTF-8

Retry logic (đúng requirements):

Tối đa 3 lần, backoff: 1s → 5s → 15s
Mỗi lần retry: tăng attempt_smtp, status = SMTP_RETRYING
Hết retry: status = FAILED, ghi last_error
Thành công: status = COMPLETED

SMTP delivery:

net/smtp.SendMail với PlainAuth
Địa chỉ: SMTP_HOST:SMTP_PORT
From: SYSTEM_EMAIL

Wiring (`cmd/bridge/main.go`)

smtpSender.SendReplyFunc() → api.NewRouter(..., onDone)
Callback handler gọi onDone(task) async sau khi trả response

Pipeline hoàn chỉnh 🎉

IMAP IDLE → RECEIVED → AI_PROCESSING → (OpenClaw callback) → CALLBACK_DONE → SMTP reply → COMPLETED
                ↓           ↓                                                    ↓
             IGNORED      FAILED                                               FAILED

Tất cả transitions đã được implement:

IMAP → RECEIVED ✅
RECEIVED → AI_PROCESSING ✅
AI_PROCESSING → CALLBACK_DONE ✅
CALLBACK_DONE → SMTP_RETRYING → COMPLETED/FAILED ✅
Anti-loop/Whitelist → IGNORED ✅
Retry exhausted → FAILED ✅

Files thay đổi

Mới: internal/mail/smtp.go
Cập nhật: cmd/bridge/main.go (wire SMTP sender)
