Launch non-www material on the Docker Elastic Bean Stitch container

I want to run an SMTP server in a Docker container in Elastic Beanstalk, so in my Docker file I found port 25 (and other ports)

EXPOSE 25

I also edited the beanstalk download balancer (using EC2 web admin) and added port 25 to it:

| LB Protocol | LB Port | Instance Protocol | Instance Port | SSL |
|    TCP      |   25    |        TCP        |        25     | N/A |
....

And edited the instance security group to allow incoming TCP traffic to port 25 (to allow all locations to connect directly to the instance).

It doesn't seem to work. If I use the same Docker file in Virtualbox (using the option -p 25:25), I can connect to port 25 through the host machine and listen to the SMTP server. If I start the container in Elastic Beanstalk using the above configuration, I cannot connect to port 25 without using load balancing or directly EC2 instance.

Any ideas what I'm doing wrong here?
