Connect with heroku

[johnmara]

Hello, I'm using Play Framework 2.5 and I've deployed my app on Heroku.
The problem is that the same configuration that works locally, is not working on heroku.
Specifically my application.conf file contains:

play.mailer {
  host=smtp.gmail.com
  port=465
  ssl=yes
  user="[email protected]"
  password=mypassword
}

And my method which sends the email contains:

    public Result madebyme(){
        Email email = new Email();
        email.setSubject("Welcome to my app");
        email.setFrom("My app<[email protected]");
        email.addTo("<[email protected]>");
        email.setBodyText("A text message");
        mailerClient.send(email);
        return ok();
    }

When sending from heroku I get the error:

Hello @johnmara I think you need to enable "less secure apps" on your Gmail account: https://www.google.com/settings/security/lesssecureapps

There's an open issue to be able to use a more secure authentication mechanism #97

[ggrossetie]

You should also follow this guide to understand why the authentication failed: https://support.google.com/accounts/answer/6009563

In your case, you are trying to authenticate from a new location (Heroku).

@johnmara Is it working now ? Can I close this issue ?

[johnmara]

Finally I used sendgrid and worked without a problem.

Ok so this is definitely related to a configuration issue with Gmail.
I'm closing this issue 😄

You have to check two important things when you want to send emails via Gmail smtp:

1. Your apps configuration:

• host: smtp.gmail.com
• port: 587 or 465 (587 for tls, 465 for ssl)
• protocol: tls or ssl
• user: [email protected]
• password: YOUR_PASSWORD

2. The given Gmail account settings:

• If you've turned on 2-Step Verification for your account, you might need to enter an App password.
• Without 2-Step Verification:
  1. Allow less secure apps access to your account.
  2. Visit http://www.google.com/accounts/DisplayUnlockCaptcha and sign in with your Gmail username and password.
