# Vert.x Mail service (SMTP client implementation)

Vert.x service for sending SMTP emails via the vert.x event bus by a mail service running on another machine on the local network.

## MailService

The MailService interface supports sending mails through another server running on the local network by the event bus.

To use this project, add the following dependency to the dependencies section of your build descriptor:

- Maven (in your `pom.xml`):

    <dependency>
     <groupId>io.vertx</groupId>
     <artifactId>vertx-mail-service</artifactId>
     <version>3.9.0</version>
    </dependency>

- Gradle (in your `build.gradle` file):

    compile io.vertx:vertx-mail-service:3.9.0

### Service client

The service client only needs the name of the service address as parameter, the default is "vertx.mail".

    var MailService = require("vertx-mail-js/mail_service");
    var mailService = MailService.createEventBusProxy(vertx, "vertx.mail");

The behaviour of MailClient and MailService is the same, if you like you can use the MailClient interface to store the MailService instance.

A more complete example for sending a mail via the event bus is this:

    var MailService = require("vertx-mail-js/mail_service");
    var mailService = MailService.createEventBusProxy(vertx, "vertx.mail");

    var email = {
      "from" : "user@example.com",
      "bounceAddress" : "bounce@example.com",
      "to" : "user@example.com"
    };

    mailService.sendMail(email, function (result, result_err) {
      console.log("mail finished");
      if (result_err == null) {
        console.log(result);
      } else {
        console.log("got exception");
        result_err.printStackTrace();
      }
    });

## Service listener

To run the service listener that sends the mails, you need to start it separately e.g. with the vertx command

    vertx run service:io.vertx.mail-service

or deploy the verticle inside your program.

If you have a smtp server running on the machine on port 25, you can use the default config.
