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.

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`.

Rust MCP server for IMAP/SMTP. SMTP send + IMAP read with RFC-correct headers,
|
||||||
|
multipart/alternative when HTML is included, multipart/mixed for attachments,

Replaces the `scripts/kayos_mail.py` CLI path that lived in `kayos/openclaw-workspace` since 2026-04-23.
|
threading via `In-Reply-To` / `References`.
|
||||||
|
|
||||||
## 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.

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