Yes. Unless the commandprompt server is configured to use SMTP AUTH
(which in the case of cmd could be an exception, but it can't be the
rule of course)

And yes, I'm aware that quite a number of people won't like that, but
doing similar things cuts a *lot* of spam at other sites I manage.

Anyway. Cutting mail from the list address to the list address will also
help, and it's certainly a good thing to do if we can't "go all the
way".
