Bouncing and Sender: header

My question here is whether my problem is a bug in mutt(1),
the esmtp MTA or the MS Exchange server...

I am unable to bounce email from my laptop, because the original
Sender: header is retained, and the MS Exchange server refuses
to accept email with a foreign Sender:.

I use esmtp as MTA, which connects to exchange via SMPTS.

Should mutt or esmtp have removed the original Sender:, or
is it correct to retain it and Exchange should have accepted it?
Secondly, is it possible to reconfigure mutt and/or esmptrc
to drop this header when a message is bounced?

I will be grateful for any pointers.
TIA

You might insert a filter in $sendmail as wrapper before/ around
your real MTA to manipulate it however you want.
