I was going to suggest something of the sort as I've used the technique
before.  So, I'll observe that no one, that I recall, advised NOPOST,
as in  QUIET SET listname NOPOST for *@*houston.rr.com   or whatever.
People advised NOMAIL and DELETE but I don't recall seeing NOPOST.
I would have have set nopost and nomail fist thing, then try to sort it
out.  Of course, NOPOST will bounce all those items right back to them,
but maybe they'll get the message there is something wrong.
