In this  context, "Owner"  and "Owners" both  mean "any  owner". Keywords
that  tell LISTSERV  who  is  allowed to  do  what  generally allow  both
singular and plural forms, with  the same meaning (plural). Keywords that
tell it who  should get a copy  of what usually act  differently with the
singular and plural forms.
 
I don't know why the messages fall  into a black hole. I suspect they may
not be reaching LISTSERV, or the owner  may be served out, or the list is
held, etc. If a message is rejected, it goes to the owners.
