Hello again,

does is mean adding -f like this?

....
open (MAIL, "|$mail_prog -oi -t -f");
....

can injest a "fake" return-path in all sent emails if the line below was present, or is the "return-path" added by the receiving party?

....
print MAIL qq|Return-Path: <$agent_email>\n|;
....

I fond some documentation at http://www.exim.org/exim-html-4.10/doc/html/spec_13.html#IX929 regarding return_path_remove
but it seems like it works for received emails, not sent ones.

Quote below:

return_path_remove
Type: boolean
Default: true

RFC 2821, section 4.4, states that an SMTP server must insert a Return-path: header line into a message when it makes a "final delivery". The Return-path: header preserves the sender address as received in the MAIL command. This description implies that this header should not be present in an incoming message. If return_path_remove is true, any existing Return-path: headers are removed from messages at the time they are received. Exim's transports have options for adding Return-path: headers at the time of delivery. They are normally used only for final local deliveries.

You need to use the -f option on the Exim command line. The return path
exists in the message envelope, and is only added to the message header on
final delivery. Before then it is stripped: see the documentation for
return_path_remove.
