a Forwarder either forwards or delivers -- it's the same machine whichever it does. I've recast this for clarity.
For a very long time -- long before RFC5581 -- the terms MTA and MDA have distinguished between relaying and delivering.
The differences between these two activities -- and what the rights and responsibilities are in performing them -- have warranted the architectural distinction and differential labeling. No matter what machine they are on.
Similarly, the difference between simple relaying to an unmodified destination address, versus gateway/intermediary functions that take delivery, do various kinds of message manipulation, and then re-post the message to a new address, has equally warranted architectural distinction and differential labeling -- in spite of inconsistencies in the labeling.
It appears the practice in the DKIM2 effort is to conflate all these, and using a term that is thereby ambiguous.
