Gmail:

Edit scripts/email.js and change:

host: 'smtp.gmail.com'  // SMTP
host: 'imap.gmail.com'  // IMAP

Enable 2FA and create App Password: https://myaccount.google.com/apppasswords

Outlook/Hotmail:

Edit to use smtp.office365.com / outlook.office365.com
Port 587 for SMTP (TLS)

📖 Usage

Send Email

./scripts/email.js send "[email protected]" "Subject" "Email body text"

Example:

./scripts/email.js send "[email protected]" "Weekly Report" "Attached is this week's summary."

Read Recent Emails

./scripts/email.js read [limit]

Examples:

# Read last 5 emails (default)
./scripts/email.js read

# Read last 20 emails
./scripts/email.js read 20

Output includes:

UID (unique ID for moving)
From/To addresses
Subject and date
Attachment count and details
Email body preview (first 500 chars)

Advanced Search

./scripts/email.js search [options]

Search Options:

Option	Description	Example
`--from <email>`	Filter by sender	`--from "[email protected]"`
`--subject <text>`	Filter by subject keywords	`--subject "invoice"`
`--since <date>`	Emails after date	`--since "Jan 1, 2026"`
`--before <date>`	Emails before date	`--before "Feb 1, 2026"`
`--unseen`	Only unread emails	`--unseen`
`--seen`	Only read emails	`--seen`
`--body <text>`	Search in body (slow!)	`--body "meeting"`
`--limit <n>`	Max results	`--limit 10`

Examples:

# Find unread emails from specific sender
./scripts/email.js search --from "[email protected]" --unseen

# Search by subject
./scripts/email.js search --subject "invoice" --limit 5

# Date range search
./scripts/email.js search --since "Jan 15, 2026" --before "Feb 1, 2026"

# Search in body (use sparingly - can be slow)
./scripts/email.js search --body "quarterly review"

# Combine multiple filters
./scripts/email.js search --from "[email protected]" --subject "urgent" --unseen --limit 3

List Folders

./scripts/email.js folders

Shows hierarchical tree of all IMAP folders with attributes.

Example output:

📁 INBOX
📁 Sent
📁 Archive
📁 Drafts
📁 Spam
📁 Trash

Move Email to Folder

./scripts/email.js move <uid> <folder-name>

Important:

Get the uid from read or search output
Folder name is case-sensitive
Script validates folder exists before moving

Examples:

# First, find the email and note its UID
./scripts/email.js search --from "[email protected]"
# Output shows: UID: 12345

# Move to Archive folder
./scripts/email.js move 12345 "Archive"

# Move to custom folder
./scripts/email.js move 67890 "Projects/Work"

Error handling:

If folder doesn't exist, shows list of available folders
Validates UID exists before attempting move

Help

./scripts/email.js help

Shows complete usage guide with all commands and examples.

🎯 Use Cases

Daily Email Triage

# Check unread emails
./scripts/email.js search --unseen --limit 10

# Move newsletters to folder
./scripts/email.js search --from "[email protected]" --limit 1
./scripts/email.js move <uid> "Newsletters"

Find Specific Email

# Search by sender and subject
./scripts/email.js search --from "[email protected]" --subject "proposal"

# Search by date
./scripts/email.js search --since "Jan 20, 2026" --subject "meeting notes"

Archive Old Emails

# Find old read emails
./scripts/email.js search --before "Dec 1, 2025" --seen --limit 50

# Move each to Archive (use UID from output)
./scripts/email.js move <uid> "Archive"

Check for Attachments

# Read recent emails and see attachment info
./scripts/email.js read 10

# Search output automatically shows:
# - Number of attachments
# - Filename, type, and size for each

🔒 Security

Credentials never logged or stored in files
TLS/SSL encryption for all connections
App Passwords recommended over account passwords
No data leaves your machine except IMAP/SMTP connections

⚙️ Configuration

Default configuration is optimized for Zoho Mail EU.

To use another provider, edit scripts/email.js:

// SMTP Configuration
const smtpConfig = {
  host: 'smtp.your-provider.com',
  port: 465,  // or 587 for TLS
  secure: true,  // true for SSL (465), false for TLS (587)
  auth: {
    user: EMAIL_USER,
    pass: EMAIL_PASS
  }
};

// IMAP Configuration
const imapConfig = {
  imap: {
    user: EMAIL_USER,
    password: EMAIL_PASS,
    host: 'imap.your-provider.com',
    port: 993,
    tls: true,
    authTimeout: 20000
  }
};

🚀 Performance Notes

Body search (--body) can be slow on large mailboxes - use sparingly
Subject/From search is fast - uses IMAP server-side filtering
Date filters are efficient
Limit results with --limit for faster responses

🐛 Troubleshooting

"Authentication failed"

Verify EMAIL_USER and EMAIL_PASS are set correctly
Use App Password, not account password
Check provider settings (2FA, less secure apps, etc.)

"Folder not found"

Use folders command to see exact folder names
Folder names are case-sensitive
Some providers use different names (e.g., "Sent Items" vs "Sent")

"Connection timeout"

Check firewall/network settings
Verify IMAP/SMTP ports are accessible
Try increasing authTimeout in config

"No emails found"

Check search criteria
Verify emails exist in INBOX (not other folders)
Try broader search (remove some filters)

Folder organization: List folders first to plan your organization strategy
