- This opens another can of worms.
- There is a lot of automated software that can be broken by mailing lists.
- What would be nice is an RFC for mailing lists.
- Something that could describe the behavior of the list management
- software (such as how it deals with "Return-Receipt-To:"), header
- definitions (such as "Listname:" to identify the list(s) ), and some
- facilities to ease the integration of mailing lists into news systems.

- The list management software should acknowledge the receipt of the message
- by sending an appropriate notice, and then remove the
- "Return-Receipt-To:" header before forwarding the message.

- The temptation is there to try and use what already exists to some extent,
- but there appears to be a lot of interest in something with more
- functionality.
-
- Perhaps the existing functionality of sendmail's "Return-Receipt-To:"
- should be captured in an RFC, but then the idea should be extended to also
- include a "Read-Receipt-To:" header (or equivalent) for the MUA. This new
- header could then include added features (such as dealing with multiple
- recipients).
-
- As to the issue of whether "Return-Receipt-To:" has any value: yes, it
- will be less meaningful until it is standardized and becomes ubiquitous.
- But isn't that always the case with protocols?
-
- What should happen when crossing a gateway, and there is no equivalent to
- a "Return-Receipt-To:" or "Read-Receipt-To:" on the other side? Should the
- gateway send an appropriate message?
