This code uses the imap-simple library to connect to an IMAP server and append a new email to the 'Drafts' mailbox. It requires the user's email address, password, and IMAP server hostname, and uses Transport Layer Security (TLS) encryption to establish a secure connection.

Overview

This code connects to an IMAP server using the imap-simple library and appends a new email to the 'Drafts' mailbox.

Breakdown

Importing Library

var imaps = require('imap-simple');

Imports the imap-simple library and assigns it to the imaps variable.

Configuring IMAP Connection

var config = {
    imap: {
        user: 'your@email.address',
        password: 'yourpassword',
        host: 'imap.gmail.com',
        port: 993,
        tls: true,
        authTimeout: 3000
    }
};

Defines the IMAP connection configuration:

• user: The email address used for authentication.
• password: The password used for authentication.
• host: The IMAP server hostname (in this case, Gmail's IMAP server).
• port: The IMAP server port number (993 for Gmail).
• tls: Whether to use Transport Layer Security (TLS) encryption (true in this case).
• authTimeout: The authentication timeout in milliseconds (3000 in this case).

Connecting to IMAP Server

imaps.connect(config).then(function (connection) {
    //...
});

Establishes a connection to the IMAP server using the provided configuration.

Appending Email to Drafts Mailbox

const message = `Content-Type: text/plain
To: jhannes@gmail.com
Subject: Hello world
 
Hi
This is a test message
`;
connection.append(message.toString(), {mailbox: 'Drafts', flags: '\\Draft'});

Creates a new email message as a string and appends it to the 'Drafts' mailbox:

• message: The email message string.
• connection.append(): Appends the email message to the specified mailbox.
• mailbox: 'Drafts': Specifies the mailbox to append the email to (in this case, the 'Drafts' mailbox).
• flags: '\\Draft': Specifies the email flags (in this case, setting the email as a draft).
