# Himalaya Configuration Reference
Configuration file location: `~/.config/himalaya/config.toml`
## Minimal IMAP + SMTP Setup
```toml
[accounts.default]
email = "user@example.com"
display-name = "Your Name"
default = true
# IMAP backend for reading emails
backend.type = "imap"
backend.host = "imap.example.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "user@example.com"
backend.auth.type = "password"
backend.auth.raw = "your-password"
# SMTP backend for sending emails
message.send.backend.type = "smtp"
message.send.backend.host = "smtp.example.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.backend.login = "user@example.com"
message.send.backend.auth.type = "password"
message.send.backend.auth.raw = "your-password"
```
## Password Options
### Raw password (testing only, not recommended)
```toml
backend.auth.raw = "your-password"
```
### Password from command (recommended)
```toml
backend.auth.cmd = "pass show email/imap"
# backend.auth.cmd = "security find-generic-password -a user@example.com -s imap -w"
```
### System keyring (requires keyring feature)
```toml
backend.auth.keyring = "imap-example"
```
Then run `himalaya account configure <account>` to store the password.
## Gmail Configuration
```toml
[accounts.gmail]
email = "you@gmail.com"
display-name = "Your Name"
default = true
backend.type = "imap"
backend.host = "imap.gmail.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "you@gmail.com"
backend.auth.type = "password"
backend.auth.cmd = "pass show google/app-password"
message.send.backend.type = "smtp"
message.send.backend.host = "smtp.gmail.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.backend.login = "you@gmail.com"
message.send.backend.auth.type = "password"
message.send.backend.auth.cmd = "pass show google/app-password"
```
**Note:** Gmail requires an App Password if 2FA is enabled.
## iCloud Configuration
```toml
[accounts.icloud]
email = "you@icloud.com"
display-name = "Your Name"
backend.type = "imap"
backend.host = "imap.mail.me.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "you@icloud.com"
backend.auth.type = "password"
backend.auth.cmd = "pass show icloud/app-password"
message.send.backend.type = "smtp"
message.send.backend.host = "smtp.mail.me.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.backend.login = "you@icloud.com"
message.send.backend.auth.type = "password"
message.send.backend.auth.cmd = "pass show icloud/app-password"
```
**Note:** Generate an app-specific password at appleid.apple.com
### iCloud + Custom Domains (iCloud+)
When using a custom domain with iCloud+, the IMAP login username is **often your primary iCloud username** (the part before `@icloud.com`), NOT the custom domain email address. The SMTP username needs the **full email address** including the custom domain.
This is the #1 reason custom domain iCloud setups fail — clients auto-detect "iCloud" and try `full@customdomain.com` as the IMAP login, which Apple's IMAP server rejects.
```toml
[accounts.icloud-custom]
email = "name@deinedomain.de"
display-name = "Your Name"
backend.type = "imap"
backend.host = "imap.mail.me.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "deinprimär" # <-- PRIMARY iCloud username ONLY (no @icloud.com)
backend.auth.type = "password"
backend.auth.cmd = "pass show icloud/app-password"
message.send.backend.type = "smtp"
message.send.backend.host = "smtp.mail.me.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.login = "name@deinedomain.de" # <-- FULL custom domain email for SMTP
message.send.backend.auth.type = "password"
message.send.backend.auth.cmd = "pass show icloud/app-password"
```
**Troubleshooting:** Apple docs say the IMAP username is "usually the name of your iCloud Mail email address (for example, johnappleseed, not johnappleseed@icloud.com)". If the bare username doesn't work, fall back to the full email address.
## Folder Aliases
Map custom folder names:
```toml
[accounts.default.folder.alias]
inbox = "INBOX"
sent = "Sent"
drafts = "Drafts"
trash = "Trash"
```
## Multiple Accounts
```toml
[accounts.personal]
email = "personal@example.com"
default = true
# ... backend config ...
[accounts.work]
email = "work@company.com"
# ... backend config ...
```
Switch accounts with `--account`:
```bash
himalaya --account work envelope list
```
## Notmuch Backend (local mail)
```toml
[accounts.local]
email = "user@example.com"
backend.type = "notmuch"
backend.db-path = "~/.mail/.notmuch"
```
## OAuth2 Authentication (for providers that support it)
```toml
backend.auth.type = "oauth2"
backend.auth.client-id = "your-client-id"
backend.auth.client-secret.cmd = "pass show oauth/client-secret"
backend.auth.access-token.cmd = "pass show oauth/access-token"
backend.auth.refresh-token.cmd = "pass show oauth/refresh-token"
backend.auth.auth-url = "https://provider.com/oauth/authorize"
backend.auth.token-url = "https://provider.com/oauth/token"
```
## Additional Options
### Signature
```toml
[accounts.default]
signature = "Best regards,\nYour Name"
signature-delim = "-- \n"
```
### Downloads directory
```toml
[accounts.default]
downloads-dir = "~/Downloads/himalaya"
```
### Editor for composing
Set via environment variable:
```bash
export EDITOR="vim"
```

# Message Composition with MML (MIME Meta Language)
Himalaya uses MML for composing emails. MML is a simple XML-based syntax that compiles to MIME messages.
## Basic Message Structure
An email message is a list of **headers** followed by a **body**, separated by a blank line:
```
From: sender@example.com
To: recipient@example.com
Subject: Hello World
This is the message body.
```
## Headers
Common headers:
- `From`: Sender address
- `To`: Primary recipient(s)
- `Cc`: Carbon copy recipients
- `Bcc`: Blind carbon copy recipients
- `Subject`: Message subject
- `Reply-To`: Address for replies (if different from From)
- `In-Reply-To`: Message ID being replied to
### Address Formats
```
To: user@example.com
To: John Doe <john@example.com>
To: "John Doe" <john@example.com>
To: user1@example.com, user2@example.com, "Jane" <jane@example.com>
```
## Plain Text Body
Simple plain text email:
```
From: alice@localhost
To: bob@localhost
Subject: Plain Text Example
Hello, this is a plain text email.
No special formatting needed.
Best,
Alice
```
## MML for Rich Emails
### Multipart Messages
Alternative text/html parts:
```
From: alice@localhost
To: bob@localhost
Subject: Multipart Example
<#multipart type=alternative>
This is the plain text version.
<#part type=text/html>
<html><body><h1>This is the HTML version</h1></body></html>
<#/multipart>
```
### Attachments
Attach a file:
```
From: alice@localhost
To: bob@localhost
Subject: With Attachment
Here is the document you requested.
<#part filename=/path/to/document.pdf><#/part>
```
Attachment with custom name:
```
<#part filename=/path/to/file.pdf name=report.pdf><#/part>
```
Multiple attachments:
```
<#part filename=/path/to/doc1.pdf><#/part>
<#part filename=/path/to/doc2.pdf><#/part>
```
### Inline Images
Embed an image inline:
```
From: alice@localhost
To: bob@localhost
Subject: Inline Image
<#multipart type=related>
<#part type=text/html>
<html><body>
<p>Check out this image:</p>
<img src="cid:image1">
</body></html>
<#part disposition=inline id=image1 filename=/path/to/image.png><#/part>
<#/multipart>
```
### Mixed Content (Text + Attachments)
```
From: alice@localhost
To: bob@localhost
Subject: Mixed Content
<#multipart type=mixed>
<#part type=text/plain>
Please find the attached files.
Best,
Alice
<#part filename=/path/to/file1.pdf><#/part>
<#part filename=/path/to/file2.zip><#/part>
<#/multipart>
```
## MML Tag Reference
### `<#multipart>`
Groups multiple parts together.
- `type=alternative`: Different representations of same content
- `type=mixed`: Independent parts (text + attachments)
- `type=related`: Parts that reference each other (HTML + images)
### `<#part>`
Defines a message part.
- `type=<mime-type>`: Content type (e.g., `text/html`, `application/pdf`)
- `filename=<path>`: File to attach
- `name=<name>`: Display name for attachment
- `disposition=inline`: Display inline instead of as attachment
- `id=<cid>`: Content ID for referencing in HTML
## Composing from CLI
### Interactive compose
Opens your `$EDITOR`:
```bash
himalaya message write
```
### Reply (opens editor with quoted message)
```bash
himalaya message reply 42
himalaya message reply 42 --all # reply-all
```
### Forward
```bash
himalaya message forward 42
```
### Send from stdin
```bash
cat message.txt | himalaya template send
```
### Prefill headers from CLI
```bash
himalaya message write \
-H "To:recipient@example.com" \
-H "Subject:Quick Message" \
"Message body here"
```
## Tips
- The editor opens with a template; fill in headers and body.
- Save and exit the editor to send; exit without saving to cancel.
- MML parts are compiled to proper MIME when sending.
- Use `himalaya message export --full` to inspect the raw MIME structure of received emails.

# `message read` Behavior Notes
## TUI vs Subprocess — Context-Dependent
**Skill states** that `message read` hangs because it uses an interactive TUI. However, in practice (June 2026, cron job context):
```bash
# This DID work and returned body content:
himalaya message read 49830 --folder INBOX
# Output: ~3000 chars of decoded email body
# This also worked:
himalaya message read 49826 --folder INBOX
# Output: ~1100 chars
```
**When `message read` works from subprocess:**
- Terminal-like environment (not truly headless — `TERM`/`STY`/`TMUX` may be set)
- Email bodies are small-to-medium (< 10KB)
- No special characters that trigger interactive prompts
**When `message read` will likely fail:**
- True headless environment with no TTY allocation
- Large emails (> 20KB) that trigger pagination
- Emails with HTML attachments that trigger rendering prompts
**Safe default:** If `message read` works, use it. If it returns nothing or hangs, fall back to `message export --full` (see himalaya skill).
## `message export --full` as Fallback
When `message read` fails:
```python
result = subprocess.run(
["himalaya", "message", "export", msg_id, "--full"],
capture_output=True, text=True,
encoding="latin-1", timeout=30
)
```
Output is raw MIME — parse headers by splitting on `\n\n`, then decode MIME-encoded headers with `email.header.decode_header()`.
## Email Classification Patterns (Order vs Invoice)
| Signal | Likely Type |
|--------|-------------|
| Subject: "Bestellung erfolgreich", "Bestellung wurde bestätigt", "Your order is being processed" | Bestellbestätigung |
| Subject: "Deine Bestellung wird bald eintreffen", "Order coming soon", "Wir packen Deine Bestellung" | Bestellbenachrichtigung (delivery, not invoice) |
| Contains Bestellnummer/Order number + Artikel/Items + Preis but NO Rechnungsnummer/Gesamtbetrag/Steuern | Bestellbestätigung → `Bestellungen_jjjj_mm` |
| Contains Rechnungsnummer, Gesamtbetrag, Steuern, Fälligkeitsdatum | Rechnung → `Rechnungen_jjjj_mm` |
| Subject: "20 % Rabatt", "Sonderangebot", "Aktion" with discount code in body | Marketing/Newsletter → ignore |
| Subject: "Sendung kommt heute", "Live verfolgen" with DHL/Paketdienst | Versandtracking → ignore |
| Subject: "Bestellung hat einen lokalen Boost erhalten" with product recommendations | Marketing → ignore |
| Subject: "Ihre Sendung kommt heute" with DHL/Paketdienst | Versandtracking → ignore |
## `folder create` vs `message move` for Nested Folders
In practice (June 2026 cron session):
- `himalaya folder create "Rechnungen_2026_06"` returned exit code 1 with empty stderr — appeared to silently fail or succeed
- `himalaya folder create "Rechnungen_2026_06/Bestellungen_2026_06"` same behavior
- `himalaya folder list` showed the folders existed after `message move` — suggesting `message move` auto-created them
- Safe pattern: always use `message move "Parent/Child" <ID>` for nested paths, and check `folder list` to confirm
## `imap_codec` Warnings
During `message move`, `WARN imap_codec::response: Rectified missing text to "..."` may appear between the command and the success message. These are harmless IMAP protocol quirks. The actual output ends with `Message(s) successfully moved from INBOX to FolderName!`.
