They both need to be accessible by MUAs in order to act as servers, therefore they expose public endpoints on specific TCP ports (see. [_Understanding the ports_](https://github.com/tomav/docker-mailserver/wiki/Understanding-the-ports) for more details). Those endpoints _may_ be secured, using an encryption scheme and TLS certificates. When it comes to the specifics of email exchange, we have to look at protocols and ports enabled to support all the identified purposes. There are several valid options and they've been evolving overtime.
