Regarding this question, I have other. Dont ask why bu tI have this at
cleanup:
/^Received:.*/x IGNORE
/^x400-received:.*/x IGNORE
/via/x IGNORE
/mail-from/x IGNORE

So we get rid of return path.
As a consecuence we have that sender User wont realize that his email has a
problem in case destination reject it.


can anyone confirm this asseveration?

Thanx

No. The Return-Path: header is added at the time of FINAL delivery.

No, you don't get rid of Return-Path. This header is added at the
time of FINAL delivery.

No, the error is reported to the ENVELOPE sender address,
as required by the Internet mail standards.

This is the address in the SMTP "MAIL FROM" command. This address
is not copied from a message HEADER.
