Focused Email settings reference for the four SHOW rows, installed limits, manifest subscription source, redaction, precedence, timing, and the read-only boundary. Read when interpreting settings rows.
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 settings reference
Call `email(action="settings", input={}, reasoning="inventory Email policy")` to
show effective Email policy. It is SHOW-only: non-empty input is refused, no writer
exists, and it performs no mailbox I/O. Success is `{"settings": [...]}` with
exactly `key`, `current`, `default`, `configurable`, and `comment` in every row.
The complete response is bounded at 65,536 UTF-8 bytes. If applied truth or a
provider row is unavailable, the whole action fails with fixed
`SETTINGS_UNAVAILABLE`, never partial rows or exception detail.
## Installed-code rows
These three values come from Email's installed `settings.py` constants. There is
no environment/owner-file override; changing them needs reviewed code/package
bytes plus full relaunch, then another SHOW. Their row order is the order below.
## Send body character limit
`send.body_char_limit`: current/default 50,000, configurable false. Counts Unicode
body characters for send/reply; oversize bodies are refused before scheduling.
## Repeated authorized mail
There is no recipient/body repetition heuristic. Identical authorized sends
and replies remain separate deliveries; elapsed time, body novelty, or manager

How to install
mdr add lingtai-ai/lingtai-kernel/email-manual-settings-reference@sha256:8c8bb952e88da5e3The line at the top of this page pins the label v1.0.0, 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.
