Return-path is a header added by the final receiving MTA, from the SMTP
envelope sender. That's your only way of influencing it. If the message
already has one, the receiving MTA will remove it
From RFC 2821:
"When the delivery SMTP server makes the "final delivery" of a
message, it inserts a return-path line at the beginning of the mail
data. This use of return-path is required; mail systems MUST support
it. The return-path line preserves the information in the <reverse-
path> from the MAIL command. Here, final delivery means the message
has left the SMTP environment. Normally, this would mean it had been
delivered to the destination user or an associated mail drop, but in
some cases it may be further processed and transmitted by another
mail system."
