Problems sending email with JavaMail

I'm developing a Java Web application with PrimeFaces in which I use javaMail to send mail with user information, but it's giving error.

The Bean:

@Named
@RequestScoped
public class EnvioEmailBean implements Serializable {

    private static final long serialVersionUID = 1L;

    @Inject
    private Mailer mailer;

    @Inject
    @EnvioEdicao
    private Usuario usuario;

    public void enviarEmail(){
        MailMessage message = mailer.novaMensagem();

        message.to(this.usuario.getEmail())
        .subject("Informações de acesso ao sistema")
        .bodyHtml("<strong>Login:</strong> "+ this.usuario.getEmail() + 
                " com sua senha: ").send();

        FacesUtil.addInfoMessage("E-mail enviado com sucesso!");
    }

}

MailConfiguration

public class MailConfigProducer {

    @Produces
    @ApplicationScoped
    public SessionConfig getMailConfig() throws IOException {
        Properties props = new Properties();

        props.load(getClass().getResourceAsStream("/mail.properties"));

        SimpleMailConfig config = new SimpleMailConfig();
        config.setServerHost(props.getProperty("mail.server.host"));
        config.setServerPort(Integer.parseInt(props.getProperty("mail.server.port")));
        config.setEnableSsl(Boolean.parseBoolean(props.getProperty("mail.enable.ssl")));
        config.setAuth(Boolean.parseBoolean(props.getProperty("mail.auth")));
        config.setUsername(props.getProperty("mail.username"));
        config.setPassword(props.getProperty("mail.password"));

        return config;
    }

}

And finally ...

mail.server.host=smtp.gmail.com

mail.server.port=465

mail.enable.ssl=true

mail.auth=true

mail.username=******@gmail.com

mail.password=********

The error that appears is.

I did not test your code, but port to Google SMTP using SSL is the 587, this may be the problem with your code.

A complete example of how to send mail using javax.mail can be seen here .

Update:

I forgot to tell you that when you change the port to 587 you should set the SSL setting to false and TSL to true. You can check a detailed code at the link above and in this SO response .

And I also noticed that in the property names stmp is missing, the correct names should look like this:

mail.smtp.starttls.enable -> true
mail.smtp.host -> smtp.gmail.com
mail.smtp.user -> nome de usuário da conta do gmail
mail.smtp.password  -> senha
mail.smtp.port -> 587
mail.smtp.auth -> true
