No, and it won't work because sendmail does not add that to the top of
every message. It only adds it when it delivers the message to a mailbox.
It does not add it during transport or queue, so it will not be added when
MailScanner feeds it to SA.

Read the RFCs in the Return-Path header. Only delivery agents are intended
to add this.
