Well, wait a minute.  If you're talking about how an individual client
handles this, that's strictly up to the client.  LISTSERV can send a
"Reply-To:" header till the cows come home, but if the client doesn't
recognize it and uses the "From:", "Sender:", or even the RFC821 MAIL FROM:
as the reply address, there's not much LISTSERV can do about that.

I thought the complaint was that LISTSERV wasn't setting the Reply-To:
header correctly to begin with, which you can test by simply looking at
the list's archives.  I <know> <that> works properly.

You might want to try IETFHDR in these cases where it doesn't seem to
work on a given client.
