<p>Sends the <code>msg.payload</code> as an email, with a subject of <code>msg.topic</code>.</p>
|
|
<p>The default message recipient can be configured in the node, if it is left
|
|
blank it should be set using the <code>msg.to</code> property of the incoming message. If left blank
|
|
you can also specify any or all of: <code>msg.cc</code>, <code>msg.bcc</code>, <code>msg.replyTo</code>,
|
|
<code>msg.inReplyTo</code>, <code>msg.references</code>, <code>msg.headers</code>, or <code>msg.priority</code> properties.</p>
|
|
<p>You may optionally set <code>msg.from</code> in the payload which will override the <code>userid</code>
|
|
default value.</p>
|
|
<h3>Gmail users</h3>
|
|
<p>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>.</p>
|
|
<h3>Details</h3>
|
|
<p>The payload can be html format. You may supply a separate plaintext version using <code>msg.plaintext</code>.
|
|
If you don't and <code>msg.payload</code> contains html, it will also be used for the plaintext.
|
|
<code>msg.plaintext</code> will be ignored if <code>msg.payload</code> doesn't contain html.</p>
|
|
<p>If the payload is a binary buffer then it will be converted to an attachment.
|
|
The filename should be set using <code>msg.filename</code>. Optionally <code>msg.description</code> can be added for the body text.</p>
|
|
<p>Alternatively you may provide <code>msg.attachments</code> which should contain an array of one or
|
|
more attachments in <a href="https://nodemailer.com/message/attachments/" target="_new">nodemailer</a> format.</p>
|
|
<p>If required by your recipient you may also pass in a <code>msg.envelope</code> object, typically containing extra from and to properties.</p>
|
|
<p>If you have own signed certificates, Nodemailer can complain about that and refuse sending the message. In this case you can try switching off TLS.</p>
|
|
<p><b>Note</b>: uses SMTP with SSL to port 465.</p>
|
|
<h3>Use secure connection</h3>
|
|
<p>If enabled the connection will use TLS when connecting to server. If disabled then TLS is used if server supports the STARTTLS extension. In most cases set this to enabled if you are connecting to port 465. For port 587 or 25 keep it disabled.</p>

<p>Repeatedly gets emails from a POP3 or IMAP server and forwards on as a msg if not already seen.</p>
|
|
<p>The subject is loaded into <code>msg.topic</code> and <code>msg.payload</code> is the plain text body.
|
|
If there is text/html then that is returned in <code>msg.html</code>. <code>msg.from</code> and <code>msg.date</code> are also set if you need them.</p>
|
|
<p>Additionally <code>msg.header</code> contains the complete header object including
|
|
<i>to</i>, <i>cc</i> and other potentially useful properties.</p>
|
|
<p>It can optionally mark the message as Read (default), Delete it, or leave unmarked (None).</p>
|

<p>Uses the <a href="https://github.com/mscdex/node-imap/blob/master/README.md" target="_new">node-imap module</a> - see that page for
|
|
information on the <code>msg.criteria</code> format if needed.</p>
|
|
<p>Any attachments supplied in the incoming email can be found in the <code>msg.attachments</code> property. This will be an array of objects where
|
|
each object represents a specific attachments. The format of the object is:</p>
|
|
<pre>
|
|
{
|
|
contentType: // The MIME content description
|
|
fileName: // A suggested file name associated with this attachment
|
|
transferEncoding: // How was the original email attachment encodded?
|
|
contentDisposition: // Unknown
|
|
generatedFileName: // A suggested file name associated with this attachment
|
|
contentId: // A unique generated ID for this attachment
|
|
checksum: // A checksum against the data
|
|
length: // Size of data in bytes
|
|
content: // The actual content of the data contained in a Node.js Buffer object
|
|
// We can turn this into a base64 data string with content.toString('base64')
|
|
}
|
|
</pre>
|
|
<p><b>Note</b>: For POP3, the default port numbers are 110 for plain TCP and 995 for SSL. For IMAP the port numbers are 143 for plain TCP and 993 for SSL.</p>
|
|
<p><b>Note</b>: With option 'STARTTLS' an established plain connection is upgraded to an encrypted one. Set to 'always' to always attempt connection upgrades via STARTTLS, 'required' only if upgrading is required, or 'never' to never attempt upgrading.</p>
|
|
<p><b>Note</b>: The maximum refresh interval is 2147483 seconds (24.8 days).</p>

<p>Mail Transfer Agent - listens on a port for incoming SMTP mails.</p>
|
|
<p><b>Note</b>: Default configuration is "NOT for production use" as security is not enabled.
|
|
This is primarily for local testing of outbound mail sending, but could be used
|
|
as a mail forwarder to a real email service if required.</p>
|
|
<p>To use ports below 1024, for example 25 or 465, you may need to get privileged access.
|
|
On linux systems this can be done by running
|
|
<pre>sudo setcap 'cap_net_bind_service=+eip' $(which node)</pre>
|
|
and restarting Node-RED. Be aware - this gives all node applications access to all ports.</p>
|
|
<h3>Security</h3>
|
|
<p>When <i>Secure connection</i> is checked, the connection will use TLS.
|
|
If not it is still possible to upgrade clear text socket to TLS socket by checking <i>Start TLS</i>.
|
|
In most cases when using port 465, check <i>Secure connection</i>. For port 587 or 25 keep it disabled, use <i>Start TLS</i> instead.</p>
|
|
<p>If you do no specify your own certificate (path to file) then a pregenerated self-signed certificate is used. Any respectful client refuses to accept such certificate.</p>
|
|
<h3>Authentication</h3>
|
|
<p>Authentication can be enabled (PLAIN or LOGIN). Add at least one user.</p>
|
|
<h3>Expert</h3>
|
|
<p>All options as described in <a href="https://nodemailer.com/extras/smtp-server/" target="_new">nodemailer SMTP server</a> can be made here.</p>
