  That depends on your intent.  My use of the phrase "delivered through this 
mailing list" was deliberate.  Mails sent privately do not deliver through 
this list.

  I regard mail sent privately as, well, private, and separate from list
mail.  I'm not asking that anyone agree with me, but that's the way I treat
it.  I also consider people who just spam everyone they can on every reply
they make to be somewhat rude.  Excessive use of "Reply All" can cause mail
header cancer.  :)

  No, the header is correct.  The List-ID is
<gnhlug-discuss.mail.gnhlug.org>.  Just dots; no at-sign.  The List-ID is
not the same thing as the list posting address.
