# 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".

    require 'vertx-mail/mail_service'
    mailService = VertxMail::MailService.create_event_bus_proxy(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:

    require 'vertx-mail/mail_service'
    mailService = VertxMail::MailService.create_event_bus_proxy(vertx, "vertx.mail")

    email = {
      'from' => "user@example.com",
      'bounceAddress' => "bounce@example.com",
      'to' => "user@example.com"
    }

    mailService.send_mail(email) { |result_err,result|
      puts "mail finished"
      if (result_err == nil)
        puts result
      else
        puts "got exception"
        result_err.print_stack_trace()
      end
    }

## 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.
