Hi List, I am running an application which is sending mail through Postfix containing both a "From:" and a "Sender:" header.
For one specific address in "Sender:", I would like to swap the values for "From:" and "Sender:". For example: The application dispatches a message From: addre...@domain1.com Sender: addre...@domain2.com to Postfix. Before Postfix delivers the message I would like it to be changed to From: addre...@domain2.com Sender: addre...@domain1.com This swap should be done if, and only if the original "Sender:" is addre...@domain2.com, and not for any other "Sender:" address. Can this be achieved in Postfix? Regards, Lucas
