Is it possible to force empty Reply-To header in mail?

When I send mail with header like this message['Reply-To'] = '' (Python), it work fine on localhost. When I click Reply in Outlook at that received mail, To field is empty. When I send the same mail from production via company SMTP server, the mail also contains empty Reply-To header, however If I click Reply in Outlook, the address from that the mail had been received is prefilled in To field.

Is there a bug in company SMTP or why does it work only in localhost?

Thank you.

In Reply-To empty, Outlook would default to the sender address. IMHO that is how it is supposed to work.
