- I believe that it should not do so (I was once bombarded by return receipts
- after sending a bug report to one of FSF's bug-reporting addresses, which
- expanded to a mailing list).
-
- In the case of a message being manually forwarded, the forwarder should
- probably delete the Return-Receipt-To header.
-
- There are also a few ways that the message can be automatically forwarded to
- another system:
- 1) via an alias expansion
- 2) via a sendmail .forward file
- 3) by expansion into a mailing list (this is often a special case of
- alias expansion)
-
- In the case of automatic forwarding I'm not sure, however what the best approach is:
- a) if forwarding, don't send a return receipt; defer that to the system
- performing final delivery
- b) send the return receipt, but delete the Return-Receipt-To header
- before forwarding.

-
- There aren't any--Return-Receipt-To has not been standardized (to my
- knowledge), but is hard-coded into sendmail.
