node-red-node-email
|
|
===================
|
|
|
|
<a href="http://nodered.org" target="info">Node-RED</a> nodes to send and receive simple emails.
|
|
|
|
|
|
Pre-requisite
|
|
-------------
|
|
|
|
You will need valid email credentials for your email server. For GMail this may mean
|
|
getting an application password if you have two-factor authentication enabled.
|
|
|
|
**Note :** Version 1.x of this node requires **Node.js v8** or newer.
|
|
|
|
|
|
Install
|
|
-------
|
|
|
|
Version 0.x of this node is usually installed by default by Node-RED.
|
|
As long as you have at least version 0.19.x of Node-RED you can install the new version
|
|
by using the `Menu - Manage Palette` option, or running the following command in your
|
|
Node-RED user directory - typically `~/.node-red`
|
|
|
|
cd ~/.node-red
|
|
npm i node-red-node-email
|
|
|
|
GMail users
|
|
-----------
|
|
|
|
If you are accessing GMail you may need to either enable <a target="_new" href="https://support.google.com/mail/answer/185833?hl=en">an application password</a>,
|
|
or enable <a target="_new" href="https://support.google.com/accounts/answer/6010255?hl=en">less secure access</a> via your Google account settings.</p>

|
Usage
|
|
-----
|
|
|
|
Nodes to send and receive simple emails.
|
|
|
|
### Input
|
|
|
|
Repeatedly gets emails from an IMAP or POP3 server and forwards them onwards as messages 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 email *from* can be set using `msg.from` but not all mail services allow
|
|
this unless `msg.from` is also a valid userid or email address associated with
|
|
the password. Note: if `userid` or msg.from does not contain a valid email
|
|
address (userxx@some_domain.com), you may see (No Sender) in the email.
|
|
|
|
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://nodemailer.com/message/attachments/" target="_new">nodemailer</a> format.
|
|
|
|
Uses the *nodemailer* npm module.
