What was it called? I grepped ChangeLog for "Return-Receipt-To" and
"DSN" and couldn't find it.

Should I add the header as an internal note? That is to say,
something that Gnus will strip out before it sends the message? (As
with the <\# part type ...> tags that Gnus inserts when files are attached?

I believe the MTAs are responsible for making sure the DSN-requester
doesn't get flooded with messages. The Exim FAQ cited the ambiguities
in the DSN-related RFCs on this matter as their reason for not
including it. [0] 

As empirical `proof,' I have not, to my knowledge, received a flood of
receipts by posting to a mailing list with DSN enabled -- yet.
