inbox

This is a work in progress IMAP client for node.js.

The project consists of two major parts

• IMAP command parser (token based, more or less complete)
• IMAP control for accessing mailboxes (under construction)

Installation

Install from npm

npm install inbox

API

NB! This API is preliminary and may change.

Use inbox module

var inbox = require("inbox");

Create new IMAP connection

Create connection object with

inbox.createConnection(port, host, options)

where

• port is the port to the server (defaults to 143 on non-secure and to 993 on secure connection)
• host is the hostname of the server
• options is an options object for auth etc.
• options.secureConnection is a Boolean value to indicate if the connection is initially secure or not
• options.auth is an authentication object
• options.auth.user is the IMAP username
• options.auth.pass is the IMAP password
• options.auth.XOAuth2 (optional) is either an object with {user, clientId, clientSecret, refreshToken} or xoauth2.createXOAuth2Generator object, see xoauth2 for details
• options.auth.XOAuthToken (optional) is either a String or inbox.createXOAuthGenerator object
• options.clientId is optional client ID params object
• options.clientId.name is is the name param etc. see rfc 2971 for possible field names

Example:

var client = inbox.createConnection(false, "imap.gmail.com", {
    secureConnection: true,
    auth:{
        user: "[email protected]",
        pass: "Nodemailer123"
    }
});

Or for login with XOAUTH2 (see examples/xoauth2)

// XOAUTH2
var client = inbox.createConnection(false, "imap.gmail.com", {
    secureConnection: true,
    auth:{
        XOAuth2:{
            user: "[email protected]",
            clientId: "8819981768.apps.googleusercontent.com",
            clientSecret: "{client_secret}",
            refreshToken: "1/xEoDL4iW3cxlI7yDbSRFYNG01kVKM2C-259HOF2aQbI",
            accessToken: "vF9dft4qmTc2Nvb3RlckBhdHRhdmlzdGEuY29tCg==",
            timeout: 3600
        }
    }
});

Or for login with XOAUTH (see examples/xoauth-3lo.js and examples/xoauth-2lo.js)

// 3-legged- oauth
var client = inbox.createConnection(false, "imap.gmail.com", {
    secureConnection: true,
    auth:{
        XOAuthToken: inbox.createXOAuthGenerator({
            user: "[email protected]",
            token: "1/Gr2OVA2Ol64fNyjZCns-bkRau5eLisbdlEa_HSuTaEk",
            tokenSecret: "ymFpseHtEnrIsuL8Ppbfnnk3"
        })
    }
});

With 2-legged OAuth, consumerKey and consumerSecret need to have proper values, vs 3-legged OAuth where both default to "anonymous".

// 2-legged- oauth
var client = inbox.createConnection(false, "imap.gmail.com", {
    secureConnection: true,
    auth:{
        XOAuthToken: inbox.createXOAuthGenerator({
            user: "[email protected]",
            requestorId: "[email protected]",
            consumerKey: "1/Gr2OVA2Ol64fNyjZCns-bkRau5eLisbdlEa_HSuTaEk",
            consumerSecret: "ymFpseHtEnrIsuL8Ppbfnnk3"
        })
    }
});

Once the connection object has been created, use connect() to create the actual connection.

client.connect();

When the connection has been successfully established a 'connect' event is emitted.

client.on("connect", function(){
    console.log("Successfully connected to server");
});

Logout and disconnect

Logout from IMAP and close NET connection.

client.close();
client.on('close', function (){
    console.log('DISCONNECTED!');
});

List available mailboxes

To list the available mailboxes use

client.listMailboxes(callback)

Where

• callback (error, mailboxes) returns a list of root mailbox object

Mailbox objects have the following properties

• name - the display name of the mailbox
• path - the actual name of the mailbox, use it for opening the mailbox
• type - the type of the mailbox (if server hints about it)
• hasChildren - boolean indicator, if true, has child mailboxes
• disabled - boolean indicator, if true, can not be selected

Additionally mailboxes have the following methods

• open ([options, ]callback) - open the mailbox (shorthand for client.openMailbox)
• listChildren (callback) - if the mailbox has children (hasChildren is true), lists the child mailboxes

Example:

client.listMailboxes(function(error, mailboxes){
    for(var i=0, len = mailboxes.length; i<len; i++){
        if(mailboxes[i].hasChildren){
            mailboxes[i].listChildren(function(error, children){
                console.log(children);
            });
        }
    }
});

Fetch a specified mailbox object

If you need to access a specific mailbox object (for creating or listing child mailboxes etc.), you can do it with

client.getMailbox(path, callback)

Where

• path is the mailbox directory path
• callback (error, mailbox) is the callback function

Example:

client.getMailbox("INBOX.Arhiiv", function(error, mailbox){
    if(mailbox && mailbox.hasChildren){
        mailbox.listChildren(console.log);
    }
});

Select a mailbox

Before you can check mailbox contents, you need to select one with

client.openMailbox(path[, options], callback)

Where

• path is the path to the mailbox (ie. "INBOX" or "INBOX/Arhiiv") or a mailbox object
• options is an optional options object
• options.readOnly - if set to true, open the mailbox in read-only mode (downloading messages does not update seen/unseen flag)
• callback (error, info) is a callback function to run after the mailbox has been opened. Has an error param in case the opening failed and a info param with the properties of the opened mailbox.

Example

client.on("connect", function(){
    client.openMailbox("INBOX", function(error, info){
        if(error) throw error;
        console.log("Message count in INBOX: " + info.count);
    });
});

Listing e-mails

Once a mailbox has been opened you can list contained e-mails with

client.listMessages(from[, limit], callback)

Where

• from is the index of the first message (0 based), you can use negative numbers to count from the end (-10 indicates the 10 last messages)
• limit defines the maximum count of messages to fetch, if not set or 0 all messages from the starting position will be included
• callback (error, messages) is the callback function to run with the message array

Example

// list newest 10 messages
client.listMessages(-10, function(err, messages){
    messages.forEach(function(message){
        console.log(message.UID + ": " + message.title);
    });
});

Example output for a message listing

[
    {
        // if uidvalidity changes, all uid values are void!
        UIDValidity: '664399135',

        // uid value of the message
        UID: 52,

        // message flags (Array)
        flags: [ '\\Flagged', '\\Seen' ],

        // date of the message (Date object)
        date: Wed, 25 Apr 2012 12:23:05 GMT,

        title: 'This is a message, may contain unicode symbols',

        // single "from:" address
        from: {
            name: 'Andris Reinman',
            address: '[email protected]'
        },

        // an array of "to:" addresses
        to: [
            {
                name: 'test nodemailer',
                address: '[email protected]'
            }
        ],

        // an array of "cc:" addresses
        cc: [
            {
                name: 'test nodemailer',
                address: '[email protected]'
            }
        ],

        messageId: '<[email protected]>',
        inReplyTo: '<[email protected]>',
        references: ['<[email protected]>','<[email protected]>'],

        // bodystructure of the message
        bodystructure: {
            '1': {
                part: '1',
                type: 'text/plain',
                parameters: {},
                encoding: 'quoted-printable',
                size: 16
            },
            '2': {
                part: '2',
                type: 'text/html',
                parameters: {},
                encoding: 'quoted-printable',
                size: 248
            },
            type: 'multipart/alternative'
        }
    },
    ...
]

NB! If some properties are not present in a message, it may be not included in the message object - for example, if there are no "cc:" addresses listed, there is no "cc" field in the message object.

Listing messages by UID

You can list messages by UID with

client.listMessagesByUID(firstUID, lastUID, callback)

Where

• firstUI is the UID value to start listing from
• lastUID is the UID value to end listing with, can be a number or "*"
• callback is the same as with listMessage

Listing flags

As a shorthand listing, you can also list only UID and Flags pairs

client.listFlags(from[, limit], callback)

Where

• from is the index of the first message (0 based), you can use negative numbers to count from the end (-10 indicates the 10 last messages)
• limit defines the maximum count of messages to fetch, if not set or 0 all messages from the starting position will be included
• callback (error, messages) is the callback function to run with the message array

Example

// list flags for newest 10 messages
client.listFlags(-10, function(err, messages){
    messages.forEach(function(message){
        console.log(message.UID, message.flags);
    });
});

Example output for a message listing

[
    {
        // if uidvalidity changes, all uid values are void!
        UIDValidity: '664399135',

        // uid value of the message
        UID: 52,

        // message flags (Array)
        flags: [ '\\Flagged', '\\Seen' ]
    },
    ...
]

Fetch message details

To fetch message data (flags, title, etc) for a specific message, use

client.fetchData(uid, callback)

Where

• uid is the UID value for the mail
• callback (error, message) is the callback function to with the message data object (or null if the message was not found). Gets an error parameter if error occured

Example

client.fetchData(123, function(error, message){
    console.log(message.flags);
});

Fetch message contents

Message listing only retrieves the envelope part of the message. To get the full RFC822 message body you need to fetch the message.

var messageStream = client.createMessageStream(uid)

Where

• uid is the UID value for the mail

Example (output message contents to console)

client.createMessageStream(123).pipe(process.stdout, {end: false});

NB! If the opened mailbox is not in read-only mode, the message will be automatically marked as read (\Seen flag is set) when the message is fetched.

Searching for messages

You can search for messages with

client.search(query[, isUID], callback)

Where

• query is the search term as an object
• isUID is an optional boolean value - if set to true perform UID SEARCH instead of SEARCH
• callback is the callback function with error object and an array of matching seq or UID numbers

Queries

Queries are composed as objects where keys are search terms and values are term arguments. Only strings, numbers and Dates are used. If the value is an array, the members of it are processed separately (use this for terms that require multiple params). If the value is a Date, it is converted to the form of "01-Jan-1970". Subqueries (OR, NOT) are made up of objects

Examples:

// SEARCH UNSEEN
query = {unseen: true}
// SEARCH KEYWORD "flagname"
query = {keyword: "flagname"}
// SEARCH HEADER "subject" "hello world"
query = {header: ["subject", "hello world"]};
// SEARCH UNSEEN HEADER "subject" "hello world"
query = {unseen: true, header: ["subject", "hello world"]};
// SEARCH OR UNSEEN SEEN
query = {or: {unseen: true, seen: true}};
// SEARCH UNSEEN NOT SEEN
query = {unseen: true, not: {seen: true}}

Returned list is already sorted and all values are numbers.

Message flags

You can add and remove message flags like \Seen or \Answered with client.addFlags() and client.removeFlags()

List flags

client.fetchFlags(uid, callback)

Where

• uid is the message identifier
• callback (error, flags) is the callback to run, gets message flags array as a parameter

Add flags

client.addFlags(uid, flags, callback)

Where

• uid is the message identifier
• flags is the array of flags to be added
• callback (error, flags) is the callback to run, gets message flags array as a parameter

Remove flags

client.removeFlags(uid, flags, callback)

Where

• uid is the message identifier
• flags is the array of flags to be removed
• callback (error, flags) is the callback to run, gets message flags array as a parameter

Example

// add \Seen and \Flagged flag to a message
client.addFlags(123, ["\\Seen", "\\Flagged"], function(err, flags){
    console.log("Current flags for a message: ", flags);
});

// remove \Flagged flag from a message
client.removeFlags(123, ["\\Flagged"], function(err, flags){
    console.log("Current flags for a message: ", flags);
});

Upload a message

You can upload a message to current mailbox with client.storeMessage()

client.storeMessage(message[, flags], callback)

Where

• message is the message to be uploaded either as a string or a Buffer.
• flags is an array of flags to set to the message (ie. ["\\Seen"])
• callback is the callback function, gets message UID and UID and UIDValitity as a param

Example

client.storeMessage("From: ....", ["\\Seen"], function(err, params){
    console.log(err || params.UIDValidity +", "+ params.UID);
});

When adding a message to the mailbox, the new message event is also raised after the mail has been stored.

Copy a message

You can copy a message from the current mailbox to a selected one with client.copyMessage()

client.copyMessage(uid, destination, callback)

Where

• uid is the message identifier.
• destination is the path to the destination mailbox
• callback is the callback function

Example

client.copyMessage(123, "[GMail]/Junk", function(err){
    console.log(err || "success, copied to junk");
});

Move a message

You can move a message from current mailbox to a selected one with client.moveMessage()

client.moveMessage(uid, destination, callback)

Where

• uid is the message identifier.
• destination is the path to the destination mailbox
• callback is the callback function

Example

client.moveMessage(123, "[GMail]/Junk", function(err){
    console.log(err || "success, moved to junk");
});

Delete a message

You can delete a message from current mailbox with client.deleteMessage()

client.deleteMessage(uid, callback)

Where

• uid is the message identifier.
• callback is the callback function

Example

client.deleteMessage(123, function(err){
    console.log(err || "success, message deleted");
});

Wait for new messages

You can listen for new incoming e-mails with event "new"

client.on("new", function(message){
    console.log("New incoming message " + message.title);
});

Complete example

Listing newest 10 messages:

var inbox = require("inbox");

var client = inbox.createConnection(false, "imap.gmail.com", {
    secureConnection: true,
    auth:{
        user: "[email protected]",
        pass: "Nodemailer123"
    }
});

client.connect();

client.on("connect", function(){
    client.openMailbox("INBOX", function(error, info){
        if(error) throw error;

        client.listMessages(-10, function(err, messages){
            messages.forEach(function(message){
                console.log(message.UID + ": " + message.title);
            });
        });

    });
});
