Why

Mutt has a great pattern language for finding messages (~f, ~s, ~d <7d, !~U, (A | B) C, …). IMAP servers can do most of the same searches, but the wire protocol is verbose and the bindings in imaplib are awkward to compose. muttlike-imap is a small CLI that translates mutt patterns into IMAP SEARCH criteria and prints the matches as JSON or a human-readable summary.

It's intentionally small and scriptable – useful as a building block for notification scripts, AI assistants, cron jobs, or one-off lookups.

Install

pip install muttlike-imap

Requires Python 3.9+. No third-party dependencies.

Shell completion

muttlike-imap ships completion scripts for zsh, bash, and fish. Add one of the following to your shell rc file:

# zsh (~/.zshrc)
eval "$(muttlike-imap --completion zsh)"

# bash (~/.bashrc)
eval "$(muttlike-imap --completion bash)"

# fish (~/.config/fish/config.fish, or just save the output)
muttlike-imap --completion fish | source

The zsh script offers per-flag tailoring (file paths for --config, (true false) for --imap-tls, env-var names for --imap-password-env, live mailbox completion via --list-mailboxes). Bash and fish provide flag-name completion plus the same enumerations where applicable.

Configure

muttlike-imap looks for connection settings in this order (highest priority first):

1. CLI flags: --imap-host, --imap-port, --imap-user, --imap-password-cmd, --imap-password-env, --imap-tls.
2. Environment variables: IMAPQUERY_HOST, IMAPQUERY_PORT, IMAPQUERY_USER, IMAPQUERY_PASS, IMAPQUERY_TLS.
3. The file pointed to by $IMAPQUERY_CONFIG, if set.
4. $XDG_CONFIG_HOME/muttlike-imap/config (defaults to ~/.config/muttlike-imap/config).
5. ~/.config/imap-smtp-email/.env: kept as a fallback for users who already have this file from the openclaw imap-smtp-email skill. See docs/openclaw.md for wiring muttlike-imap into an openclaw workspace.

A minimal config file:

IMAP_HOST=imap.example.com
IMAP_PORT=993
IMAP_USER=[e-mail]
IMAP_PASS_CMD=pass email/imap.example.com
IMAP_TLS=true

The keys can be written with the IMAP_ prefix (shown above, matches mutt and offlineimap conventions), with the IMAPQUERY_ prefix, or with no prefix at all (HOST=…); pick whichever you prefer.

Passwords

There are three ways to give muttlike-imap your password, in increasing order of how much they leak:

• IMAP_PASS_CMD=<shell command> (recommended). The command is run on every invocation; the first line of stdout is used as the password. Pair with pass, secret-tool, macOS Keychain (security find-generic-password -w), or anything else that prints a secret to stdout. The password lives only in the muttlike-imap process memory and is never written to disk or to the environment.

  Equivalent CLI flag: --imap-password-cmd "pass email/imap.example.com".

• --imap-password-env MY_VAR. Reads the password from a named environment variable. Useful when you already have a secret in a variable (e.g. via direnv or a parent process) and don't want to re-export it. Caveat: env vars leak through /proc/<pid>/environ, child processes, ps eww, and crash dumps.

• IMAP_PASS=<plaintext> in the config file. Simplest, least secure; fine for throwaway accounts and local-only setups. Make sure the file is chmod 600.

See docs/secrets.md for worked examples with pass, raw gpg, and OS keyrings.

Examples

By default the search runs against INBOX and returns the 10 most recent matches as JSON. Pass --mailbox <name> to search elsewhere, --limit N to widen or narrow the result count, and --summary for human-readable output.

# Unread mail, default INBOX, summary view
muttlike-imap "~U" --summary

# All mail from Alice in the last week
muttlike-imap "~f alice ~d <7d" --summary

# Archived correspondence with Bob about a specific topic
muttlike-imap '~L bob ~s "project x"' --mailbox Archive --summary

# Anything addressed to me, last 30 days, that I haven't replied to
muttlike-imap '~p ~d <30d !~Q' --summary

# Date range, ISO format
muttlike-imap '~d 2025-09-01-2025-12-31 ~f committee' --summary

# JSON for piping into jq
muttlike-imap "~U" | jq '.[] | {uid, subject, from}'

# Discover available folders
muttlike-imap --list-mailboxes

Pattern syntax

A B is AND (juxtaposition), A | B is OR, !A is NOT, and (...) groups.

Modifier	Meaning
~f <text>	From contains
~t <text>	To contains
~s <text>	Subject contains
~b <text>	Body contains
~B <text>	Body or any header contains
~c <text>	Cc contains
~C <text>	To, Cc, or Bcc contains
~L <text>	Any participant (From/To/Cc)
~e <text>	Sender header
~i <text>	Message-ID
~y <text>	X-Label
~h "Name: text"	Arbitrary header
~x <text>	References / In-Reply-To
~A	All messages
~U / ~N	Unread / new
~R / ~O	Read / old
~F	Flagged
~D	Deleted
~Q	Replied (answered)
~p	Addressed to you
~P	From you
~d <Nu	Date: header newer than N units (units y m w d H M S)
~d >Nu	Date: header older than N units
~d =Nu	Exactly N units old
~d DATE	On a specific date (YYYY-MM-DD or D/M/Y)
~d -DATE / ~d DATE-	Half-open range (before / since)
~d DATE-DATE	Range
~d DATE*Nu	Range of ±N units around DATE
~r DATERANGE	Same grammar but on received date (INTERNALDATE)
~z <N / ~z >N / ~z N-M	Size in bytes (suffix K/M)

Limitations vs mutt

• No regex. IMAP SEARCH is substring-only, so all text matches are literal. Anchors and character classes are not honored.
• No mutt-runtime modifiers. ~T (tagged), ~v (collapsed thread), ~m (message-number), ~n (score), ~$, ~#, ~(...) (thread patterns), PGP modifiers: all error out instead of silently misbehaving.

H/M/S offsets are exact despite IMAP's day granularity: the server narrows to the smallest whole-day window containing the precise range, then a client-side post-filter trims the fetched candidates by their Date: header (or INTERNALDATE for ~r). ~d <30M really does mean "last 30 minutes". The post-filter is suppressed when the sub-day modifier sits inside an OR, !, or paren-grouped disjunction, since lifting its predicate to a top-level filter would change the pattern's meaning.

Library use

from muttlike_imap.parser import parse_pattern
from muttlike_imap.client import search
from muttlike_imap.config import load_config

config = load_config()  # or pass in your own dict
results = search(config, "~f alice ~U", limit=10, mailbox="INBOX")
for r in results:
    print(r["subject"])

# Or just use the parser:
parse_pattern("(~f a | ~f b) ~U")
# → 'OR (FROM "a") (FROM "b") UNSEEN'
