Not sure I understand this, but if you are saying what I think you are saying, why on earth would you do this? This totally BREAKS smtp.
The null envelope sender is used for very specific reasons
he does not talk about the null envelope
he tries to send back to the not relevant from-header and ignore the envelope-sender which is not much better
do not violate SMTP
there is a reason that the return path exists
instead break RFCs please do yourself and any other mailuser on this earth which maybe randomly affected by your misconfigurations a favour and read documentations
mailservers are a dangerous playground
