Be aware that "from" addresses can easily be forged. I suggest
whitelisting a set of valid commands and executing only those. If you
want a REAL way to manage your home system remotely, I would recommend
SSH instead.

That's an improvement, but since the password is being transmitted in
clear text, it won't prevent attacks. It does mean you won't try to
execute the subject lines of random spam, though, so accidents will be
reduced (or eliminated).

Seems perfectly possible.

Seems like a reasonable start. So what's the code doing wrong, or
failing to do? Is it failing with an exception? Is it running
successfully, but not doing something you want it to do?
