API

MailDev can be used in your Node.js application. For more info view the
API docs.

``javascript
const MailDev = require('maildev')

const maildev = new MailDev()

maildev.listen()

maildev.on('new', function (email) {
// We got a new email!
})
`

MailDev also has a REST API. For more info
view the docs.

Outgoing email

Maildev optionally supports selectively relaying email to an outgoing SMTP server. If you configure outgoing
email with the --outgoing-* options you can click "Relay" on an individual email to relay through MailDev out
to a real SMTP service that will actually send the email to the recipient.

Example:

$ maildev --outgoing-host smtp.gmail.com \
--outgoing-secure \
--outgoing-user 'you@gmail.com' \
--outgoing-pass ''

$3

Enabling the auto relay mode will automatically send each email to it's recipient
without the need to click the "Relay" button mentioned above.
The outgoing email options are required to enable this feature.

Optionally you may pass an single email address which Maildev will forward all
emails to instead of the original recipient. For example, using
--auto-relay you@example.com will forward all emails to that address
automatically.

Additionally, you can pass a valid json file with additional configuration for
what email addresses you would like to allow or deny. The last matching
rule in the array will be the rule MailDev will follow.

Example:

$ maildev --outgoing-host smtp.gmail.com \
--outgoing-secure \
--outgoing-user 'you@gmail.com' \
--outgoing-pass '' \
--auto-relay \
--auto-relay-rules file.json

Rules example file:
`javascript
[
{ "allow": "*" },
{ "deny": "*@test.com" },
{ "allow": "ok@test.com" },
{ "deny": "*@utah.com" },
{ "allow": "johnny@utah.com" }
]
`
This would allow angelo@fbi.gov, ok@test.com, johnny@utah.com, but deny
bodhi@test.com.

Configure your project

Configure your application to send emails via port 1025 and open localhost:1080 in your browser.

Nodemailer (v1.0+)

`javascript
const transport = nodemailer.createTransport({
port: 1025,
ignoreTLS: true,
// other settings...
})
`

Nodemailer (v0.7)

`javascript
const transport = nodemailer.createTransport('SMTP', {
port: 1025,
// other settings...
})
`

Django -- Add EMAIL_PORT = 1025 in your settings file [[source]](https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-EMAIL_PORT)

Rails -- config settings:

`ruby
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "localhost",
:port => 1025
}
`

Drupal -- Install and configure SMTP module or use a library like SwiftMailer.

Ideas

If you're using MailDev and you have a great idea, I'd love to hear it. If you're not using MailDev because it lacks a feature, I'd love to hear that too. Add an issue to the repo here or contact me on twitter.

Contributing

Any help on MailDev would be awesome. There is plenty of room for improvement. Feel free to create a Pull Request from small to big changes.

To run MailDev during development:

npm install
npm run dev

The "dev" task will run MailDev using nodemon and restart automatically when
changes are detected. On *.scss file save, the css will also be recompiled.
Using test/send.js, a few test emails will be sent every time the application
restarts.

The project uses the JavaScript Standard coding style.
To lint your code before submitting your PR, run npm run lint`.

To run the test suite:

$ npm test
