Fastmail Suite

Use the bundled scripts (stdlib-only) to interact with Fastmail safely.

Quick start

Set credentials/tokens:

# JMAP token (Mail + Contacts scopes)
export FASTMAIL_TOKEN='…'

# CalDAV app password (calendar)
export FASTMAIL_CALDAV_USER='you@yourdomain'
export FASTMAIL_CALDAV_PASS='app-password'

# Optional: redact output (default is 1)
export FASTMAIL_REDACT=1

Verify setup:

python3 skills/fastmail-suite/scripts/suite.py status

Suite CLI (v0.2)

Status / onboarding checks

python3 skills/fastmail-suite/scripts/suite.py status

Expected style:

• Mail (JMAP): OK / MISSING TOKEN / AUTH FAILED
• Calendar (CalDAV): OK / MISSING APP PASSWORD / AUTH FAILED
• Contacts (JMAP): OK / MISSING TOKEN / AUTH FAILED

Inbox triage

python3 skills/fastmail-suite/scripts/suite.py triage today
python3 skills/fastmail-suite/scripts/suite.py triage last-7d

Triage summarizes:

• top senders,
• action-needed subject patterns (invoice, bill, payment, due, confirm, action required, reminder, ...),
• highlights for friends.tas.edu.au and bill/payment-like items.

Search

python3 skills/fastmail-suite/scripts/suite.py search "from:billing@ subject:invoice last:7d"
python3 skills/fastmail-suite/scripts/suite.py search "has:attachment before:2026-02-01 tax"
python3 skills/fastmail-suite/scripts/suite.py search "after:2026-02-01 reminder"

Supported query tokens:

• from:foo
• subject:bar
• has:attachment
• last:7d (and other Nd forms)
• before:YYYY-MM-DD
• after:YYYY-MM-DD
• Bare words → subject/body text search

Thread summary

python3 skills/fastmail-suite/scripts/suite.py thread <email-id>
python3 skills/fastmail-suite/scripts/suite.py thread <thread-id>
python3 skills/fastmail-suite/scripts/suite.py thread "school invoice"

Shows concise thread summary:

• participants,
• rough timeline,
• latest 1–2 messages with short plain-text summary.

Other existing scripts

Security & Credentials (important)

Fastmail Suite works with real Fastmail credentials, so the design is intentionally conservative.

Required

• FASTMAIL_TOKEN — Fastmail JMAP API token (Mail + Contacts scopes). Best practice is to use a read-only token for normal usage.

Optional but supported

• FASTMAIL_TOKEN_SEND — separate JMAP token with Email Submission scope for sending mail. Only used if you explicitly enable writes.
• FASTMAIL_CALDAV_USER / FASTMAIL_CALDAV_PASS — Fastmail app password for calendar (CalDAV).
• FASTMAIL_REDACT — controls redaction of output (default 1 = redacted).
• FASTMAIL_ENABLE_WRITES — when set to 1, enables write operations (send/move/update). Omit or set to 0 to keep read-only.

Safety model

• Redaction is ON by default

Output is redacted unless you pass --raw where supported. FASTMAIL_REDACT=1 is the default.

• Writes are OFF by default

The skill will not send/move/update anything unless FASTMAIL_ENABLE_WRITES=1 and you have provided appropriate tokens (for example FASTMAIL_TOKEN_SEND for sending mail).

• Separation of roles

You can keep a strict separation:

• Email reading: FASTMAIL_TOKEN
• Email sending: FASTMAIL_TOKEN_SEND (optional, only when writes are enabled)
• Calendar: FASTMAIL_CALDAV_USER + FASTMAIL_CALDAV_PASS (Fastmail app password)

• Read-only mode is fully supported

You can run the entire suite (status, triage, search, thread, contacts, calendar read) with a read-only JMAP token + calendar app password, without ever enabling writes.
