For example, the Delivery Status Notification extension defined in RFC 3461 requires a null return path when sending email with a "NOTIFY=NEVER" option to a non-conforming server. Some e-mail bounces (incorrectly) get sent not to the return address, but to the e-mail address on the From: header.
Historically, all mail transfer agents (MTAs) added their host name to the reverse path. In the Simple Mail Transfer Protocol (SMTP) this reverse path is also known as MAIL FROM, but paths were also used before and outside of SMTP, e.g. as bang paths in UUCP and Usenet (Net-News). All news articles still contain a Path header, example:
return path - When the email is put in the recipient's email box, a new mail header is created with the name "Return-Path:" containing the address on the MAIL FROM command. Earlier forms of email (such as UUCP ) would require information about each "hop" along the path that the email traveled to reach the destination, hence the "path" part of ...

If the email is bounced, a message is sent to this address, [2] and for downstream transmission it typically appears in the "Return-Path" header. To authenticate the email address which is actually visible to recipients on the "From:" line, other technologies such as DMARC must be used. Forgery of this address is known as email spoofing, [3 ...
