Focused Email reference for absolute-path addressing, reply return routes, legacy mail without a route, safe same-channel replies, sender identity display, and local mailbox-ID privacy. Read when routing or answering internal mail.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Email addressing and replies
## Addresses
Every address in `send` (`address`, `cc`, `bcc`) is an absolute agent-workdir
path, such as the `.lingtai/<name>` directory of the recipient. Bare names,
`@` addresses, and relative paths are refused before anything is written.
Verify the recipient first: its `.agent.json` must exist, and a non-human
recipient must have a fresh heartbeat. A directory whose manifest is valid with
`admin` null is the human mailbox and counts as live. Do not invent a target or
infer one from a sibling directory, a bare `from` name, or a name in a message
body. Non-self delivery and bounce limits are in
[Notifications and delivery](../notifications-and-delivery/SKILL.md).
## Replies and return routes
`reply` and `reply_all` answer the sender's absolute address, resolved in this
order:
1. the message's top-level `_return_route.address`, when it is an absolute path.
The route object is exactly `{"address": "<absolute sender workdir>",
"sender_agent_id": "<sender id, or empty>"}`. Every `send` writes it, and the
TUI writes it on human mail;
2. otherwise the message's `from`, when that is itself an absolute path;

How to install
mdr add lingtai-ai/lingtai-kernel/email-manual-addressing-and-replies@sha256:f739a988ba29c3fbThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
