It is trivial to do it with a shadow transport. I did so some time ago as a
test of shadow transports. Something like this:
xxx:
driver = autoreply
from = $local_part
to = $h_return-receipt-to
subject = message received
text = Message from <$sender_address> has reached my inbox.
user = $local_part
local_delivery:
driver = appendfile
file = /home/$local_part/inbox
delivery_date_add
envelope_to_add
return_path_add
shadow_transport = xxx
shadow_condition = $h_return-receipt-to
However, I don't myself like the idea.

Agreed. However, I have been reading the DSN RFCs, and IMHO it is far too
complex and could also be categorised as "badly thought out".
