Amazon SESを使ってメール送信

    public void sendMail() {
    try {
        AmazonSimpleEmailService ses = new AmazonSimpleEmailServiceClient(new ClasspathPropertiesFileCredentialsProvider().getCredentials());
        Region usEast1 = Region.getRegion(Regions.US_EAST_1);
        ses.setRegion(usEast1);

        SendEmailResult emailResult = ses.sendEmail(new SendEmailRequest("from@test.com", new Destination(Arrays
                .asList("to@test.com")), new Message(new Content("件名"), new Body(
                new Content("本文")))));
 System.out.println(emailResult.toString());
    } catch (Exception e) {
    }
    }

SendEmailResult でメール送信時のMessageIdが返ってきます。
