The previous problem was due to "Send= Editor, Postmaster" which with
1.7e was treated like "Send= Editor" and with 1.7f is parsed as the
person who typed it expected. Unfortunately, that is not valid. When the
list is moderated, you indicate who can post to it via the "Editor="
keyword.
I can't review RESUG-L so I can't say anything about that, except that
the "Send=" keyword is probably incorrect. Try GET (HEADER followed by
PUT with no change to have the parser validate the keywords.
