Public-flip audit: scrub Sulkta-internal refs + Browserless IPs + add LICENSE
Repository URL → git.sulkta.com. Drop Lucy Browserless IPs from tool doc-strings (replaced with abstract 'sandboxed headless browser' guidance). Drop sibling-repo cross-references, kayos@/cobb@ mailbox examples in tool descriptions, vault pointers. Generalize config.example.toml + README to neutral hosts. Add LICENSE (MIT — Cargo.toml already declared it). Tests still green. No behavior change.

# mail-mcp
|
||||
|
||||
Rust MCP server for Sulkta-hosted email. SMTP send + IMAP read with RFC-correct headers, multipart/alternative when HTML is included, multipart/mixed for attachments, threading via `In-Reply-To`/`References`.
|
||||
|
||||
Replaces the `scripts/kayos_mail.py` CLI path that lived in `kayos/openclaw-workspace` since 2026-04-23.
|
||||
|
||||
## Why a server, not a CLI
|
||||
|
||||
`kayos_mail.py` shipped without `Date` or `Message-ID` headers until a 2026-05-18 patch — exactly the kind of header-discipline regression a typed Rust server prevents at compile time. The "no spam bin" framing is mostly upstream of any client (Rackham postfix + rspamd DKIM-sign at the relay; mail-tester scored 10/10 and port25 SpamAssassin −7.31 on 2026-05-20), but a correct client doesn't trip filters with bad MIME structure, broken threading, or missing headers.
|
||||
Rust MCP server for IMAP/SMTP. SMTP send + IMAP read with RFC-correct headers,
|
||||
multipart/alternative when HTML is included, multipart/mixed for attachments,
|
||||
threading via `In-Reply-To` / `References`.
|
||||
|
||||
## Tools (v0.1)
|
||||
|
||||
- `mail_send` — send mail. Args: `account?`, `to`, `cc[]?`, `bcc[]?`, `subject`, `body`, `body_html?`, `attachments[]?`, `in_reply_to?`, `references[]?`. Returns `{message_id, sent_at}`.
|
||||
- `mail_inbox_list` — list folder messages newest-first. Args: `account?`, `since?` (YYYY-MM-DD), `unread_only?`, `limit?` (default 50, max 500), `folder?` (default INBOX). Uses `BODY.PEEK` so it does not toggle `\Seen`.
|
||||
- `mail_inbox_read` — fetch one message by UID. Args: `account?`, `uid`, `folder?`, `format?` (`text`|`html`|`raw_eml`). Attachment payloads are not inlined — only filename/mime_type/size metadata.
|
||||
- `mail_send` — `account?`, `to`, `cc[]?`, `bcc[]?`, `subject`, `body`,
|
||||
`body_html?`, `attachments[]?`, `in_reply_to?`, `references[]?`.
|
||||
Returns `{message_id, sent_at}`.
|
||||
- `mail_inbox_list` — newest-first listing. `account?`, `since?` (YYYY-MM-DD),
|
||||
`unread_only?`, `limit?` (default 50, max 500), `folder?` (default INBOX).
|
||||
Uses `BODY.PEEK` — does not toggle `\Seen`.
|
||||
- `mail_inbox_read` — fetch one message by UID. `account?`, `uid`, `folder?`,
|
||||
`format?` (`text` | `html` | `raw_eml`). Attachment payloads NOT inlined —
|
||||
only `{filename, mime_type, size}` metadata.
|
||||
|
||||
## Headers we guarantee on outbound
|
||||
## Outbound headers
|
||||
|
||||
- `Date` — UTC, RFC 5322 (lettre auto)
|
||||
- `Message-ID` — `<UUIDv4@<from_addr_domain>>` — own-domain, never the container hostname
|
||||
- `Message-ID` — `<UUIDv4@<from_addr_domain>>` — own-domain, not the
|
||||
container hostname
|
||||
- `From` — `name <addr>`
|
||||
- `MIME-Version: 1.0`
|
||||
- `User-Agent: mail-mcp/<version>`
|
||||
- `In-Reply-To` + `References` when threading args present
|
||||
- `Content-Type` correct for the body shape (text-only / alternative / mixed)
|
||||
- `Content-Type` correct for body shape (text-only / alternative / mixed)
|
||||
|
||||
DKIM-Signature is applied by the relay (rspamd on Rackham), not the client.

## Future phases
|

## Safety
|

|

- **Phase B** (~200 LOC): multi-account routing across all configured `[accounts.*]`, plus `mail_thread` and `mail_search`.

`mail_inbox_read` returns attacker-controlled bytes. Do NOT auto-fetch URLs

found in inbound mail — web beacons confirm read and links may be phishing.

Default deny on every URL; surface as text and wait for explicit per-link

authorization. If a fetch is authorized, route through a sandboxed headless
|

browser rather than `curl` / `WebFetch` from the production host. Attachment

bytes get the same treatment.
