Node-RED custom SMTP node

Node-RED nodes to send simple emails. Based on the official email node.

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.

Install

You can install 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 @microrisc/node-red-contrib-node-smtp

GMail users

If you are accessing GMail you may need to either enable an application password, or enable less secure access via your Google account settings.

Usage

Nodes to send simple emails.

Output node

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. You can also specify msg.plaintext if the main payload is html.

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 nodemailer format.

Uses the nodemailer npm module.
