I also have been playing with mailer plugin but still i am having problem since 2 days i am stuck on just this simple task. Well reading other topics seems like other people are also have problems. So like them i also followed the same config as told in the installation in play-mailer page still not able to send any email. Here is my app configuration:

play.mailer {
  host=smtp.office365.com
  port=587
  ssl=false
  tls=true
  user="l************y@outlook.com"
  password="**************"
  debug=yes
}

MailService Class wrapper (omitted importing libs just to keep the code minimal):

public class MailerService {
    MailerClient mailerClient;

    @Inject
    public MailerService(MailerClient mailerClient) {
        this.mailerClient = mailerClient;
    }

    public void sendEmail() {
        String cid = "1234";
        Email email = new Email();
        email.setSubject("Verify Account Please");
        email.setFrom("*************@outlook.com");
        email.addTo("************@gmail.com");
        email.setBodyText("ABC");

        mailerClient.send(email);
    }
}

My controller action in the play framework:

public class ApiController extends Controller {
    MailerService mailerClient;

    @Inject
    public ApiController(MailerService mailer) {
        this.mailerClient = mailer;
    }

    public Result createUser() {
      //some code for app logic and then email
      mailerClient.sendEmail();
   }
}

and i getting these exceptions:

Also i want to confirm something as i am using play without any SSL config so right now on my dev server i am accessing it locally on HTTP rather HTTPS. Does that matter that i have to be on HTTPS protocol to use this mailer plugin?

Could you try smtp.gmail.com:587 with TLS ?
I think SSL was replaced by TLS on Gmail.

Are you behind a corporate proxy ?

Tried with that as well with following settings:

play.mailer {
  host="smtp.gmail.com"
  port=587
  ssl=no
  tls=yes
  user="************************@gmail.com"
  password="*****************"
  debug=yes
}

and still getting exceptions:

Nope no proxy at all.

Are you using -Djavax.net.ssl.trustStore in your JVM arguments ? I think your truststore does not contains certification authorities.
Are you using a custom Java installation ? By default the JRE trusts all certificates that somehow link to one of the certificates in jre/lib/security/cacerts, unless you have configured a different truststore.

nah i am using the default JRE that i downloaded from the official site. So i didn't even customize any kind of arguments for JVM. Neither i have configured a custom trust store. I searched over the internet and someone suggested to put play.ws.ssl.loose.acceptAnyCertificate=true in app conf but It wasn't working. Then i also tried running application with passing the arguments activator run -Dmail.smtp.ssl.trust=* -Dmail.smtp.ssl.checkserveridentity=false which wasn't recommended but still result was failure.

Ok thanks for the information provided.
What operating system and what version of the JRE are you using ? I will try to reproduce this issue on my machine.

No problem sure here are my version and other details details:
Windows 10 Version 10.0.14393
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)

Thanks for the the quick input!

Dayummm You won't believe it i was thinking and just hit in my mind that there could be one more thing that can cause trouble that is my antivirus blocking smtp requests. Guess what i was right. I deactivated my antivirus protection and it works like a charm!

Thanks @Mogztter agian for quick replies :). Actually i think it's better to add this in the README file for windows users that if mailer is not working try closing any antivirus shields that might can lead to block smtp requests.

Just for future reference for someone who might be wondering what were my working app conf for google smtp using TLS then it is as follows:

play.mailer {
  host="smtp.gmail.com"
  port=587
  ssl=no
  tls=yes
  user="*******@gmail.com"
  password="******"
  debug=yes #for dev usage only
}

I'm glad you found the root cause.

Yes, that's a good idea!
I think we should add a troubleshooting section with the stack traces and the possible causes.
