Then stop/uninstall the software that listens on port 25 and thus
prevents postfix of doing so.

Yes, it's the command line interface to the mail system and it's called
"sendmail" because of sendmail compatibility. But postfix' sendmail

does is called "master".
Is your mail server going to be accessible from an untrusted network/the
