I did try this example. (adding reply_transport= and user=)

But when I do so, Exim tries to deliver mail to '>joe@???'
(note the angle bracket). I actually don't know where it gets this from.

Here's the setup producing this strange result:

gtnfilter:
  driver = forwardfile
  file = /root/exim/gtnfilter
  domains = mbs.gtn.com
  filter
  no_check_local_user
  no_verify
  user = root                       # else mail from filter
  reply_transport = address_reply   # won't work


after this director comes userforward.
gtnfilter contains this:

# Exim filter
mail to ${local_part}@???
     reply_to joe@???
     from postmaster@???
     subject "MBS.GTN.COM"
     once /root/exim/gtnwarn
     once_repeat 7d
     expand file /root/exim/gtn.txt
