The current version of LISTSERV implemented "Send= Owner" through the
equivalent of an OTHERWISE clause - anything unrecognized allowed the
list owners, and only them, to post. This made it possible to code "Send=
Owners" with the desired effect, even though this was never a documented
possibility. The new 1.7d code works differently, so this fails.
If there are enough people with good reasons to want "Send= Owners" to
work, I might change the code to make it work under 1.7d as well.
