There are 2 uses for command line SMTP communications: 1) Testing 2) Program usage. Do you know that SMTP communications basically take place like a command line? Just much much much faster. If the from address is local and the to address is local, it should accept. If the from address is remote and the to address is local, it should accept If the from address is local and the to address is remote, it should reject unless authenticated. If the from address is remote and the to address is remote, it should reject. That is how e-mail servers should be configured. Of course there are other configurations such as wide open or locked down, but generally that is the configuration.
