Store and forward mail but change FROM header in forwarded mail

procmail

I need a procmail recipe which stores the mail and forwards it to another address.

The following works fine:

:0c
! addressto@forward.to

But..now I need to change the From: header in the mails that are being forwarded, and I know it can probably be done with formail but I failed to find any good examples on how to do that and still store the email

EDIT:
solved it myself, see the answer below

I managed to solve it by using this recipe, and I also added a line that changes the From: address for the system where we forward it to

# store mail in default folder and continue after that
:0c
${DEFAULT}

# change header
:0fhw
| formail -i "From: fakefromaddress@forothersystem.com"

# forward mail
:0
! addressto@forward.to
