# fw-nodes-email

Email (SMTP/IMAP) nodes for Flowire workflow automation.

## Nodes

### Send Email

Send emails via SMTP with support for HTML content, CC/BCC/Reply-To headers, and file attachments (base64-encoded).

- **Credential:** SMTP (host, port, username, password, TLS/SSL)
- **Inputs:** from address, to, subject, body, optional CC/BCC/Reply-To, optional attachments
- **Outputs:** success status, message ID, recipient list

### Read Emails

Fetch emails from a mailbox via IMAP with filtering and folder selection.

- **Credential:** IMAP (host, port, username, password, SSL)
- **Inputs:** folder, IMAP search filter (e.g. `UNSEEN`, `FROM "user@example.com"`), max results, mark as read, include attachment content
- **Outputs:** list of emails (headers, plain/HTML body, attachment metadata), count, folder

### Email Trigger

Stream trigger node that fires workflows in real-time when new emails arrive via IMAP IDLE.

- **Credential:** IMAP
- **Inputs:** folder to monitor
- **Outputs:** event type, sender, recipients, subject, date, plain/HTML body, attachments, raw event
- **Stream handler:** `ImapIdleStreamHandler` — maintains a persistent IMAP IDLE connection and yields events on new mail (re-issues IDLE every 25 minutes per RFC 2177)
