RFC5321 says that when a message is delivered the envelope MAIL FROM address goes into a Return-Path header, but says nothing about the RCPT TO address. Many MTAs put that in a Delivered-To header and have done so for a long time. I know that Postfix and qmail do. It shows up in examples in RFCs 5293 and 7681.

I think this is sufficiently established that we can add it to 5321bis. We could say that the delivery SMTP server SHOULD insert a Delivered-To line when it inserts a Return-Path line, and SHOULD NOT remove existing Delivered-To lines.

This header field is not yet registered with IANA, so it needs to be registered first.

Discussion on the mailing list resulted in suggestion to do a separate draft targeted at Proposed Standard.
