How to configure outbound-socket-binding for SMTP mail in wildfly swarm for using yaml?

I am porting an application from Wildfly 10.0.1.0 to Wildly Swarm 2017.7.0.

Everything went rather smoothly except for the SMTP e-mail configuration using YAML:

I tried some alternatives, but here is the latest one based on what I think the yaml would be from standalone.xml mapping - project-defaults.yml

swarm:
  socket-binding-groups:
    mail-socket:    
      outbound-socket-bindings:
        mail-smtp:
          remote-host: smtp.someprovider.com
          remote-port: 587

  mail:
    mail-sessions:
      smtpSession:
        jndi-name: java:/smtpSession
        smtp-server:
          username: username_here
          password: password_here
          tls: true
          outbound-socket-binding-ref: mail-smtp

However I still get error:

2017-08-05 11:17:36,100 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([

}

As advised by Ladicek I tried this:

 swarm:
   socket-binding-groups:
     standard-sockets:
       mail-socket:
         outbound-socket-bindings:
           mail-smtp:
             remote-host: smtp.someprovider.com
             remote-port: 587

and

swarm:
  socket-binding-groups:
    standard-sockets:
      outbound-socket-bindings:
        mail-smtp:
          remote-host: smtp.someprovider.com
          remote-port: 587

and

swarm:
  socket-binding-groups:
    standard-socket:
      outbound-socket-bindings:
        mail-smtp:
          remote-host: smtp.someprovider.com
          remote-port: 587

However neither is working, still have the same error.

Could anyone please help on this?
