Mercedes,
My suspicions have been confirmed. With Listserv, Sender takes priority
over From. If this subscriber is subscribed under [log in to unmask]
this will keep happening as long as his mail client is inserting
"Sender: [log in to unmask]"  If the subscriber cannot change this, then it
would be best to subscribe <[log in to unmask]> and delete
<[log in to unmask]>  Or, you can have both addresses subscribed and
set one to NOMAIL.
