#MailKit 0.1#

A simple but powerful email wrapper around Nodemailer.

##Features:##

• raw html body
• basic templating engine.

##Supports##

• SMTP
• sendmail
• unicode

Setup

To set up diskspace.js on your Node.js server use npm.

    npm install {LATER!!!}

Basic Usage

if no smtp details is defined, sendmail will be used by default, this should work on Mac and Linux systems.

var mailkit = require('mailkit');

var mailOptions = {
    from: "Sender Name ✔ <[email protected]>", // sender address
    to: "lolkatz@localhost", // can also be a list: "[email protected], [email protected]"
    subject: "Hello ✔", // Subject line
    body: "<b>Hello world ✔</b>" //body
}

mailkit.send(mailOptions, function(error, status)
{
	console.log(status);
	if (error)
	{
		console.log('an error');
	}
	else
	{
		console.log('not an error!');
	}
});

error is true or false. status is an object with more details.

I recommend saving the failed emails to your database to try to resend later.

SMTP Usage

Also this demos basic templating.

var mailkit = require('mailkit');

var SMTP = {
service: "Gmail",
    auth: {
        user: "[email protected]",
        pass: "userpass"
    }
};

var mailOptions = {
    from_name: "Your name",
    from_addr: "[email protected]",
    to: "lolkatz@localhost", // can also be a list: "[email protected], [email protected]"
    subject: "Hello ✔", // Subject line,
    mime: 'html',
    view: './templates/layout.bt',
    subview: './templates/signup.bt',
    data: {year: '2012'},
    //html: "<b>Hello world ✔</b>",
    //body: "<b>Hello world ✔</b>" //body,
    smtp: SMTP
}

mailkit.send(mailOptions, function(error, status)
{
    console.log(status);
    if (error)
    {
        console.log('an error');
    }
    else
    {
        console.log('not an error!');
    }
});

Render

If you don't want to send the email, but render the body. We can do that also!

##Mail Options##

• from - Sender Name ✔ <[email protected]>
• from_addr - [email protected] //from_addr will overwrite from
• from_name - Sender Name ✔ //when using from_addr, from_name will add a name.
• to - A single address or list that will appear on the To: field
• cc - A single address or list that will appear on the CC: field
• bcc - A single address or list that will appear on the BCC: field
• replyTo - An e-mail address that will appear on the Reply-To: field
• subject - The email subject.
• mime - html or text or both. Default is html if the mime is text and you send html, the html will be displayed as text.
• body - The body, for when not using a template. Using body overrides everything in the layout section. Will be used for html and text
• html - override the body, and set your own HTML.
• text - overrides the body, and set your own text. You can use both html and text. HTML will be displayed to clients that support html, text is a failback for those that don't. If you set the mime to both and only provide html, text will be generated from the html.
• smtp - refer to the SMTP section for more details, if not defined sendmail will be used as the transporter when you send. If you wish to change your transporter(EG: SMTP details, you'll have to use a new instance of MailKit.)
• headers - An object of additional header fields {"X-Key-Name": "key value"} (values are passed as is, you should do your own encoding to 7bit if needed)
• attachments - An array of attachment objects. See attachment fields for more details.
• envelope - optional SMTP envelope, if auto generated envelope is not suitable messageId - optional Message-Id value, random value will be generated if not set. Set to false to omit the Message-Id header encoding - optional transfer encoding for the textual parts (defaults to "quoted-printable")

All text fields (e-mail addresses, plaintext body, html body) use UTF-8 as the encoding. Attachments are streamed as binary.

Layout - Template Usage:

• view - location of view file
• subview - location of subview, use {{subview}} in your view to display this. This is optionally.
• data - A Javascript object.

{
	'username': 'Kevin',
	'someother' : 'data'
}

and then in your view you use {username} to display the username.

##SMTP##

Possible SMTP options are the following:

• service - an optional well known service identifier ("Gmail", "Hotmail" etc., see Well known Services for a list of supported services) to auto-configure host, port and secure connection settings
• host - hostname of the SMTP server (defaults to "localhost", not needed with service)
• port - port of the SMTP server (defaults to 25, not needed with service)
• secureConnection - use SSL (default is false, not needed with service). If you're using port 587 then keep secureConnection false, since the connection is started in insecure plain text mode and only later upgraded with STARTTLS
• name - the name of the client server (defaults to machine name)
• auth - authentication object as {user:"...", pass:"…"} or {XOAuthToken: "base64data"}
• ignoreTLS - ignore server support for STARTTLS (defaults to false)
• debug - output client and server messages to console
• maxConnections - how many connections to keep in the pool (defaults to 5)

##SMTP envelope##

SMTP envelope is usually auto generated from from, to, cc and bcc fields but if for some reason you want to specify it yourself, you can do it with envelope property.

envelope is an object with the following params: from, to, cc and bcc just like with regular mail options. You can also use the regular address format.

mailOptions = {
    ...,
    from: "[email protected]",
    to: "[email protected]",
    envelope: {
        from: "Daemon <[email protected]>",
        to: "[email protected], Mailer <[email protected]>"
    }
}

##Attachment fields##

Attahcment object consists of the following properties:

• fileName - filename to be reported as the name of the attached file, use of unicode is allowed (except when using Amazon SES which doesn't like it)
• cid - optional content id for using inline images in HTML message source
• contents - String or a Buffer contents for the attachment
• filePath - path to a file or an URL if you want to stream the file instead of including it (better for larger attachments)
• streamSource - Stream object for arbitrary binary streams if you want to stream the contents (needs to support pause/resume)
• contentType - optional content type for the attachment, if not set will be derived from the fileName property
• contentDisposition - optional content disposition type for the attachment, defaults to "attachment"

One of contents, filePath or streamSource must be specified, if none is present, the attachment will be discarded. Other fields are optional. Attachments can be added as many as you want.

var mailOptions = {
    ...
    attachments: [
        {   // utf-8 string as an attachment
            fileName: "text1.txt",
            contents: "hello world!
        },
        {   // binary buffer as an attachment
        fileName: "text2.txt",
            contents: new Buffer("hello world!,"utf-8")
        },
        {   // file on disk as an attachment
            fileName: "text3.txt",
            filePath: "/path/to/file.txt" // stream this file
        },
        {   // fileName and content type is derived from filePath
            filePath: "/path/to/file.txt"
        },
        {   // stream as an attachment
            fileName: "text4.txt",
            streamSource: fs.createReadStream("file.txt")
        },
        {   // define custom content type for the attachment
            fileName: "text.bin",
            contents: "hello world!,
            contentType: "text/plain"
        },
        {   // use URL as an attachment
            fileName: "license.txt",
            filePath: "https://raw.github.com/andris9/Nodemailer/master/LICENSE"
        }
    ]
}

##Using Embedded Images##

Attachments can be used as embedded images in the HTML body. To use this feature, you need to set additional property of the attachment - cid (unique identifier of the file) which is a reference to the attachment file. The same cid value must be used as the image URL in HTML (using cid: as the URL protocol, see example below).

The cid value should be as unique as possible!

var mailOptions = {
    ...
    html: "Embedded image: <img src='cid:[email protected]' />",
    attachments: [{
        filename: "image.png",
        filePath: "/path/to/file",
        cid: "[email protected]" //same cid value as in the html img src
    }]
}

##Well known services for SMTP##

If you want to use a well known service as the SMTP host, you do not need to enter the hostname or port number, just use the service parameter (case sensitive).

Currently cupported services are:

• "Gmail" for Google Mail
• "hot.ee" for www.hot.ee
• "Hotmail" for Microsoft Live Hotmail
• "iCloud" for Apple iCloud
• "mail.ee" for www.mail.ee
• "Postmark" for Postmark App
• "SendGrid" for SendGrid
• "SES" for Amazon SES
• "Yahoo" for Yahoo Mail
• "Zoho" for Zoho Mail

Predefined service data covers host, port and secure connection settings, any other parameters (ie. auth) need to be set separately.
