v1.3.4

v1.3.4

Compact, self-contained tool schemas:

• Every tool definition is now self-contained: tools that need a session say Requires mail_connect, and UID parameters state that they refer to the selected mailbox (INBOX unless changed with mail_open_mailbox); previously this lived only in the server instructions.
• Tool and parameter descriptions tightened to cut the up-front tools/list token cost; descriptions that only restated a parameter name are gone. mail_search's mailbox description now states the real default (all mailboxes, not INBOX).

v1.3.3

v1.3.3

Fixes stdio stalls and hangs affecting MCP hosts (observed with Zed on Windows):

• Blocking-mode stdin hot-loop after the host closed its end of the pipe (feof() never true on Windows anonymous pipes) — orphaned server processes no longer pin a CPU core while every queued call times out.
• Un-decodable response bodies (e.g. a proxy 502 page while a backing service is down) now complete the HTTP request with a loud error instead of leaving it "in flight" forever, spinning the await loop.
• Stdin EOF no longer drops an in-flight tool response; regular-file stdin (server < request.json) degrades to blocking reads instead of hanging.
• Diagnostics now go through EnchiladaMCP Logger and are silent by default: MAIL_MCP_LOG=/path for a durable file, MAIL_MCP_LOG_STDERR=1 for a budgeted mirror, --log / --log-level / --io-mode CLI flags.

v1.3.2

v1.3.2

Fixes stdio stalls with hosts that close or never drain their pipes (observed with Zed on Windows), and makes the IMAP and OAuth paths event-driven:

• Re-vendored Tortilla StdioTransport: bounded no-EOF read retries; diagnostics go through EnchiladaMCP\Logger (silent by default, MAIL_MCP_LOG / MAIL_MCP_LOG_STDERR opt-in). Adds --log / --log-level / --io-mode flags.
• Re-vendored OAuthCallbackServer from Enchilada/Extras master (#49): handleConnection() is fully non-blocking, so the authorization-callback listener can no longer stall the MCP channel when an SSH-forwarded request trickles in.
• IMAP socket I/O is now event-driven (SocketImapClient): permanently non-blocking after connect, buffered reads, writes via writability wait (large APPEND literals included). With the reactor loop, network waits park the dispatch fiber so pings keep being answered mid-call; otherwise a bounded poll emits progress notifications. STARTTLS and async connect share the same wait machinery.
• New functional I/O test (SocketImapClientIoTest) pins the non-blocking engine against an in-process fake IMAP server.

v1.3.1

Release v1.3.1 of SecureMessage Mail MCP Server.

Changed

• OAuth token exchange/refresh HTTP moved from the blocking \EnchiladaHTTP to the loop-aware pipeline (Enchilada\Tortilla\Oauth3LOClient over HttpClient over EnchiladaMultiHTTP), enabled by the Extras OAuth/ split (Oauth3LO pure protocol core). Token waits now fiber-park under the reactor or poll with progress notifications on blocking stdio. Token semantics, persistence format, and PKCE are unchanged.

v1.3.0

Release v1.3.0 of SecureMessage Mail MCP Server.

Changed

• Enchilada transport split: EnchiladaMCP re-vendored as the slim protocol core; stdio transport now comes from the new Enchilada\Tortilla library with the event loop opt-in wired in the composition root (bin/mail-mcp). Comal is vendored, so the transport runs in reactor mode where pollable — the OAuth callback listener continues to be serviced continuously during the interactive authorization flow
• HTTP library classes vendor at libraries/EnchiladaHTTP/ and libraries/EnchiladaMultiHTTP/ (eponymous dirs the framework autoloader resolves natively — no guarded require_once); EnchiladaMultiHTTP gained setVerifySsl/setTimeout/setPlaintextAuth/setCaCert parity setters and getResult() diagnostics

v1.2.0

Release v1.2.0 of SecureMessage Mail MCP Server.

Upgrade Notes

Breaking: mail_reply now defaults to reply-to-all (reply_all: true) and draft-first (draft: true). Replies are no longer sent immediately — pass draft: false explicitly to send right away. include_original remains true.

Install

curl -LO https://pacyworld.dev/securemessage/mail-mcp/releases/download/v1.2.0/mail-mcp.phar
chmod +x mail-mcp.phar

Added

• attachments parameter on mail_reply — attach files to replies, consistent with mail_send and mail_create_draft (#19)
• Missing-attachment heuristic (#19): if the body contains an attachment phrase but no files are attached, mail_send refuses to send unless force: true is passed; mail_create_draft and mail_reply include a warning field in the response without blocking
• force parameter on mail_send — override the missing-attachment block (#19)
• mail_update_draft — modify an existing draft (recipients, subject, body, attachments) without losing threading headers or quoted history (#22)

Changed

• Re-vendored Enchilada MCP library: protocol version negotiation (2025-06-18 support), unknown-tool calls return tool-level errors with closest-name suggestions, outputSchema/renamedFrom tool metadata, structured content results, ToolWarningInterface support
• Re-vendored EnchiladaHTTP: multipart form format support, getLastCurlErrno()/getLastCurlError() accessors
• File attachment handling refactored into shared Mail\AttachmentHelper class

v1.1.6

Fixed

• mail_search multi-mailbox path now slices UIDs to limit per mailbox before fetching headers, matching the single-mailbox path (#18)
• mail_search multi-mailbox loop now fails fast on connection-level errors (connection lost, timeout) instead of stalling through all remaining mailboxes (#17)
• Stale IMAP connections detected via NOOP probe after 60s of inactivity, triggering auto-reconnect instead of silently using a dead socket (#17)

Install

curl -LO https://pacyworld.dev/securemessage/mail-mcp/releases/download/v1.1.6/mail-mcp.phar
chmod +x mail-mcp.phar

v1.1.5

Added

• from key in instance configuration — explicit RFC 5322 From address (with optional display name) separate from the SMTP/IMAP auth username (#16)

Fixed

• mail_send, mail_reply, mail_create_draft no longer emit an invalid From: header when the login username is not an email address (#16)
• MessageBuilder::setFrom() now validates that the value contains an addr-spec (has @), failing loudly at build time instead of silently producing an RFC 5322-invalid message (#16)
• SMTP envelope sender (MAIL FROM / Return-Path) now uses the resolved from address for DMARC domain alignment (#16)

Install

curl -LO https://pacyworld.dev/securemessage/mail-mcp/releases/download/v1.1.5/mail-mcp.phar
chmod +x mail-mcp.phar

v1.1.4

Changes

Added

• mail_get_headers — raw RFC 5322 header block inspection

Fixed

• mail_create_draft with in_reply_to now includes quoted original message body (#14)
• Reply-all no longer corrupts addresses when display names contain commas (#12, #13)
• IMAP reconnect after transient auth error no longer fails due to stale connection state (#15)

Install

curl -LO https://github.com/securemessage/mail-mcp/releases/download/v1.1.4/mail-mcp.phar
chmod +x mail-mcp.phar

v1.1.3

EnchiladaMCP graceful lifecycle: onReinitialize hook for IDE multi-session resilience, stdout write failure detection.
