I understand your perspective, but this is actually by design. The default Ubuntu Server install opens no ports to the outside world (which is also why openssh is an option and not in the standard install). While I understand the problems associated with this design choice, it is unlikely to change since no open ports by default is a very long standing policy (and so no MTA by default). The alternative is to select the mail server task and you'll get a Postfix you can easily configure for this use case.
