XMPP SMTP Gateway

A xmpp gateway to send emails from your xmpp messenger.

Description

I needed a simple and lightweight xmpp -> smtp gateway, but could not find a good one. This module enables me to send simple emails right from my chat messenger.

Architecture

• No–frills
• Support for subject & body as specified in RFC 3921 and RFC 6121
• Support for html content: XEP 0071
• Support for XEP-0106: JID Escaping as email adress e.g. user@host.com is represented as jid user\40host.com@smtp.example.com
• support for in-line XEP-0231: Bits of Binary attachments
• Outbound SMTP gateway only
• No templating because we support XEP 0071
• Run as XEP-0114: Jabber Component or XEP-0220: Server Dialback

Run it

# install it as a global component
npm install -g xmpp-smtp-gw
xmpp-smtp-gw configfile

# start it from the installation directory
node bin/xmpp-smtp-gw config/component.json
# start with debugging
DEBUG=* node bin/xmpp-smtp-gw config/component.json

# This project also ships with a `Procfile` and plays well 
# with foreman 
foreman start 

foreman enables you to generate upstart scripts for your node project. Further information is available at UPSTART-EXPORT

Configuration

This module delivers as a XMPP component () or XMPP s2s component. Both components behave similar.

Notes

Be aware that it this module does not generate different content types for images. Either use inline images via data urls or use external hosted images.

Tests

Grunt

The gateway comes with jshint and mocha test. Just run

grunt test

Vagrant

The integration with prosody is tested with vagrant and Ubuntu 12.04.

vagrant up

This will:

• Boot up Ubuntu 12.04
• Install Prosody
• Prepares Prosody to accept a component smtp.example.com (Prosody config) or talk with an domain xmppsmtpgateway.com (bind dns config) via a server-2-server connection.

Afterwards you need to add the following entry to your hosts file in /etc/hosts:

192.168.55.10   example.com

Once you got this try to ping example.com and you should see a connection to 192.168.55.10. As a next step you need to configure the SMTP server in config/component.json and config/s2s.json. Just add the server and the mailbox credentials in mailer.config

Now we are ready to prepare the XMPP messages. Configure test/client/component/message.xml and test/client/s2s/message.xml with a proper target. e.g. change romeo\40example.com@smtp.example.com to youremail@smtp.example.com. The local part of the jid needs to be escaped according to XEP-0106: JID Escaping.

Test the XMPP Component

vagrant ssh
cd /vagrant
foreman start

# open a new terminal and start
node test/client/component/send.js

Test the XMPP Server-2-Server

# on your machine 
DEBUG=* node bin/xmpp-smtp-gw config/s2s.json

# open a new terminal and start
node test/client/s2s/send.js

Send messages from XMPP messenger

If you would like to send emails directy from your xmpp client, configure the user me@example.com with the password me in your favorite XMPP messenger and send a message to user\40host.com@smtp.example.com (component) or user\40host.com@xmppsmtpgateway.com depending on the setup you use.
