+node-red-node-email
+===================
+
+<a href="http://nodered.org" target="_new">Node-RED</a> nodes to send and receove simple emails.
+
+**Note** : This is the same node as is/was in the core of Node-RED. If you already
+have it installed you do NOT need this node.
+
+Pre-requisite
+-------------
+
+You will need valid email credintials for your email server.
+
+Install
+-------
+
+Run the following command in the root directory of your Node-RED install.
+Usually this is `~/.node-red` .
+
+        npm install node-red-node-email
+
+Usage
+-----
+
+Nodes to send and receive simple emails.
+
+###Input
+
+Repeatedly gets a **single email** from an IMAP server and forwards on as a msg if not already seen.
+
+The subject is loaded into **msg.topic** and **msg.payload** is the plain text body.
+If there is text/html then that is returned in **msg.html**. **msg.from** and
+**msg.date** are also set if you need them.
+
+Additionally **msg.header** contains the complete header object including
+**to**, **cc** and other potentially useful properties.
+
+**Note:** this node *only* gets the most recent single email from the inbox,
+so set the repeat (polling) time appropriately.
+
+Uses the *imap* npm module.
+
+###Output
+
+Sends the **msg.payload** as an email, with a subject of **msg.topic**.
+
+The default message recipient can be configured in the node, if it is left
+blank it should be set using the **msg.to** property of the incoming message.
+
+The payload can be html format.
+
+If the payload is a binary buffer then it will be converted to an attachment.
+
+The filename should be set using **msg.filename**. Optionally
+**msg.description** can be added for the body text.
+
+Alternatively you may provide **msg.attachments** which should contain an array of one or
+more attachments in <a href="https://www.npmjs.com/package/nodemailer#attachments" target="_new">nodemailer</a> format.
+
+Uses the *nodemailer* npm module.
