☤CaduceusMail 3.6.7

Inbox-reliability optimization engine: automates sender trust hardening, identity rotation, and scale-ready outreach/support flows designed to keep your mail out of junk.

☤CaduceusMail is a shippable skill for enterprise-grade alias/domain control on top of a single Microsoft 365 mailbox and Cloudflare DNS zone.

OpenClaw skill adapter for an audited caduceusmail release artifact vendored inside this skill. It manages M365 + Cloudflare mail/DNS without a runtime npm fetch.

What this does

This skill is a thin adapter around the standalone caduceusmail package. On first use the wrapper:

1. Verifies the vendored tarball against a pinned SHA-512 integrity value in vendor/caduceusmail-release.json
2. Extracts the audited release into a skill-owned cache under ~/.local/share/caduceusmail-skill/toolchains
3. Runs the CLI with a reduced environment and owner-only permissions on runtime state directories

It does not fetch code from npm at runtime, install a global package, or execute npm lifecycle scripts.

First move

Run the doctor through the secure wrapper before you do anything theatrical.

bash {baseDir}/scripts/run.sh doctor --json

Quick start

bash {baseDir}/scripts/run.sh bootstrap \
  --organization-domain "example.com" \
  --mailbox "ops@example.com" \
  --bootstrap-auth-mode device

Daily headless run after bootstrap

bash {baseDir}/scripts/run.sh bootstrap \
  --organization-domain "example.com" \
  --mailbox "ops@example.com" \
  --skip-m365-bootstrap

Lane operations

bash {baseDir}/scripts/run.sh provision-lane \
  --mailbox "ops@example.com" \
  --local "support" \
  --domain "support-reply.example.com"

bash {baseDir}/scripts/run.sh verify-lane \
  --mailbox "ops@example.com" \
  --alias-email "support@support-reply.example.com" \
  --domain "support-reply.example.com"

bash {baseDir}/scripts/run.sh retire-lane \
  --mailbox "ops@example.com" \
  --alias-email "support@support-reply.example.com"

Hard Rules

• never send group emails from one operation
• never send one message to multiple recipients at once
• treat no-reply lanes as intentional non-receiving identities (no MX + SPF -all profile)
• delete defaults are reply-safe: aliases are retired with fallback continuity unless explicitly hard-removed

What this skill can do

• bootstrap Graph and Exchange auth posture
• hand off Microsoft device-login flows for VPS/SSH setups through OpenClaw gateway/browser hooks
• audit credential and DNS posture
• optimize root mail records
• provision reply and no reply lanes under subdomains
• verify lane readiness
• retire lanes with reply continuity
• generate awareness snapshots and machine readable state artifacts

OpenClaw runtime pattern

Prefer secret injection through skills.entries.caduceusmail.env over editing files. See examples/openclaw.config.json5. The wrapper forwards only the CaduceusMail/OpenClaw/M365/Cloudflare variables it needs plus terminal/headless hints, so unrelated host secrets are not passed through by default. External script resolution stays disabled unless CADUCEUSMAIL_ALLOW_EXTERNAL_SCRIPT_RESOLUTION=1 is set explicitly.

Security and Privilege Disclosure

This skill performs high-privilege operations by design:

• Microsoft Graph app role grants
• Exchange service principal and RBAC role assignments
• Exchange accepted-domain tuning (optional flags)
• Cloudflare DNS mutations for lane records

Runtime state artifacts are written under ~/.caduceusmail/intel with owner-only permissions. Env/secret persistence remains opt-in in the underlying tool, and any persisted env file is expected to stay owner-readable only. Use least-privilege credentials: a dedicated Entra service principal scoped to the required Graph/Exchange roles and a Cloudflare token limited to the target zone's DNS permissions.
