There are hardly any circumstances where you should be
including a list of users with the PUT listname.
 
The proper technique (for what you are trying to accomplish)
is:
 
GET listname (HEAD
 
(wait for output)
 
(receive output to a file)
 
(update headers in file)
 
LSVPUT (or e-mail as approp) the headers back to LISTSERV
 
QUIET SET listname options FOR userid@node
 
where userid@node can be any valid wild-card notion or explicit.
