Modified to work on Thunderbird 60.7

Redirect action in the filters. Difference between "redirect" and "forward" is that in the redirected email the field "From" contain the email writer address.

To use it, go to Tools->Message Filters-> Create and choose action "Redirect to". You can set default redirect options in Tools->Add-ons-> RedirectFilter -> Preferences. Also you can set custom redirect options by using button * That is on the right of field for redirect to address in the filter editor dialog.

Additional information you can find on the addon home page.
