# 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.

### Service client

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

    import io.vertx.groovy.ext.mail.MailService
    def 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:

    import io.vertx.groovy.ext.mail.MailService
    def mailService = MailService.createEventBusProxy(vertx, "vertx.mail")

    def email = [
      from:"user@example.com",
      bounceAddress:"bounce@example.com",
      to:"user@example.com"
    ]

    mailService.sendMail(email, { result ->
      println("mail finished")
      if (result.succeeded()) {
        println(result.result())
      } else {
        println("got exception")
        result.cause().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.
